Embryo Transfer Explained: Your Complete Guide to the Big Day

Embryo Transfer Explained: Your Complete Guide to the Big Day

There’s a moment in the IVF journey that many describe as powerful — the embryo transfer. After weeks, sometimes months or years of preparation, this day represents more than a procedure. It’s the bridge between hope and possibility. 

At The Center for Advanced Reproductive Services (CARS), we see embryo transfer day as a shared milestone — one where science, medicine, compassion, and trust come together. Your care team is here to make sure you feel informed, supported, and fully present as you take this meaningful next step. 

Before Your Embryo Transfer 

The day begins with preparation — both for your body and your heart. Your care team will confirm your medication schedule, timing, and embryo details so everything is aligned for success. 

You’ll also receive reminders for the morning of your transfer: 

• Avoid perfumes, hairsprays, and scented lotions — embryos are sensitive to air quality. 

• Arrive with a comfortably full bladder (it helps us guide the catheter under ultrasound). 

• You’re welcome to bring a partner, loved one, or support person for comfort. 

• If you’d like, you can explore pre- or post-transfer acupuncture to encourage relaxation. 

What Happens During Embryo Transfer 

The transfer itself is short and gentle — usually 10 to 15 minutes. You’ll lie comfortably while your fertility specialist uses ultrasound to guide a very thin, soft catheter through your cervix and into your uterus. Your embryo is placed with care and precision. 

You may see it happen in real time on the monitor — a tiny flash of light as the embryo is released, carried in a small bubble of fluid. That bright moment represents more than biology; it’s possibility in motion. 

Most people describe the feeling as similar to a Pap test — slight pressure but not pain. No anesthesia is needed, and you’ll be awake and able to share the moment with your support person if you wish. 

Your CARS reproductive endocrinologist stays connected throughout, explaining each step so you always know what’s happening. 

What Comes Next: After Embryo Transfer 

After your transfer, you’ll rest for a short time before heading home. You can expect mild cramping, bloating, or spotting — all normal signs that your body is responding to the procedure. 

Here are a few gentle guidelines for the days that follow: 

• Follow your medication plan carefully (these hormones help support early implantation). 

• Avoid heavy lifting or intense exercise. Light walking or yoga is fine. 

• Hold off on intercourse until your pregnancy test. 

• Hydrate, eat well, and rest when your body asks. 

Most importantly, try to be kind to yourself during the “two-week wait.” The urge to analyze every twinge or symptom is human — but your body and your embryo are doing quiet, remarkable work right now. 

During this period, it can be tempting to take a pregnancy test. We advise you to wait until your appointment with CARS, during which we’ll perform bloodwork to confirm the pregnancy.  

What is Single-Embryo Transfer? 

Today’s embryo transfer techniques have evolved dramatically. In the early days of IVF, it was common to transfer multiple embryos to increase the chance of pregnancy — but that also increased the risk of multiple gestations, which can lead to health complications for both the parent and baby. 

Research from the American Society for Reproductive Medicine (ASRM) shows that transferring a single, healthy embryo (called elective single-embryo transfer, or eSET) offers the same success rates as transferring multiple embryos while significantly lowering the risk of twins or higher-order pregnancies.* 

(While it might be tempting to think that twins would mean having the completed family of your dreams, there is significant research showing that single pregnancies allow for healthier pregnancies and outcomes.) 

That’s why at CARS and across the First Fertility network, we follow evidence-based single-embryo transfer practices — prioritizing your safety, your health, and the goal of one healthy baby at a time. 

Frequently Asked Questions

How is my transfer day scheduled?

The timing depends on whether your cycle is a fresh or frozen embryo transfer. Your physician and embryologist coordinate based on your body’s readiness, hormone levels, and embryo development.

Is single-embryo transfer right for everyone?

For most hopeful parents, yes. Single-embryo transfer maintains excellent success rates while reducing pregnancy-related risks. Your CARS physician will personalize this recommendation to your situation.

What’s the difference between fresh and frozen embryo transfer?

A fresh transfer typically happens a few days after egg retrieval. A frozen embryo transfer (FET) takes place later, allowing your body to recover and your hormones to be precisely balanced. Both approaches have strong outcomes; your team will help determine which is right for you. 

Build the Family of Your Dreams with CARS 

Embryo transfer isn’t just the “final” step in IVF — it’s a new beginning. You’ve prepared your mind, your body, and your heart for this moment, and your care team has prepared everything else. 

At The Center for Advanced Reproductive Services, we’re honored to share this milestone with you — combining leading-edge reproductive science with care that centers your comfort, dignity, and hope.

Is Acetaminophen Safe During Pregnancy?

According to the American College of Obstetricians and Gynecologists (ACOG), acetaminophen is considered safe to use during pregnancy when taken as directed. This guidance can offer peace of mind when managing common discomforts such as headaches, mild pain, or fever.

As always, it’s important to follow dosing instructions and consult your healthcare provider before starting or continuing any medication during pregnancy. Your health and peace of mind matter. Let this serve as one more reassurance as you move forward in your pregnancy journey.

Signs of Pregnancy After IVF

For individuals and couples undergoing IVF, the period after an embryo transfer can feel very long and often difficult as you wait for confirmation of pregnancy. For many, this 10–14-day time period can quickly become an emotionally draining process.

Understanding the early signs of pregnancy, such as fatigue, spotting, cramping, and nausea, is crucial, especially for those who have undergone IVF. These symptoms, while less common with traditional conception, can occur as the embryo implants and begins to grow, empowering you with the knowledge you need during this emotional time. 

It’s important to remember: Early pregnancy symptoms can vary widely—and it’s completely normal to have none at all, especially during this stage of your fertility journey. That said, focusing on small, healthy choices you can control (such as prioritizing restful sleep, choosing nourishing foods, gentle movement if approved by your fertility provider, and caring for your emotional well-being through mindfulness or support networks) may feel more grounding than tracking symptoms or taking early pregnancy tests—especially since those tests are often unreliable and can cause unnecessary emotional ups and downs during IVF or other fertility treatments.

While every body experiences pregnancy differently, here are some signs that could indicate pregnancy after IVF treatment. 

Bleeding or Spotting

One of the early signs of pregnancy after IVF can be light bleeding or spotting, often referred to as implantation bleeding. Implantation bleeding occurs when the embryo burrows into the uterine lining. This process usually happens around six to 12 days after conception.

The duration and intensity of spotting can vary but is generally much lighter than a regular menstrual period. This bleeding may appear as a pink or brownish discharge and usually lasts a day or two. It’s a common response to feel a moment of panic—but understanding why this is happening can offer reassurance that it’s actually a healthy sign, not an indication that something’s wrong.

If spotting is accompanied by severe pain, that should be checked out by a medical professional.

Cramping 

Another common early sign of pregnancy after IVF is mild cramping. This cramping can be related to the implantation process and will likely not be as intense as typical menstrual cramps. A sensation of pulling or stretching in the lower abdomen can sometimes accompany it.

Cramps are normal parts of the implantation process, during which the embryo settles into the uterine lining. If you feel cramping, breathe, this can be just a normal part of the early pregnancy process.

Sore Breasts

Hormonal changes brought on by pregnancy can also lead to sore or tender breasts. This symptom occurs due to the surging levels of the hormones estrogen and progesterone, which prepare the body for lactation. Wearing a good, supportive bra, alongside warm compresses, can help alleviate any soreness you may experience.

Tiredness or Fatigue

Fatigue is one of the most common early signs of pregnancy and can be particularly noticeable after an IVF procedure. The body's increased effort to support the developing embryo, coupled with rising levels of progesterone, can lead to feelings of extreme tiredness.

Lifestyle changes like prioritizing sleep, staying hydrated, and maintaining a balanced diet can help manage these feelings of tiredness. It's also important to listen to your body and avoid overexertion during this time.

False Symptoms of Pregnancy after Embryo Transfer

It is possible to experience symptoms that mimic the early signs of pregnancy without being pregnant. The exact cause of these false pregnancy symptoms is not completely understood, but it is believed to result from a complex interaction of psychological, hormonal, and physical factors.

To distinguish between a true and false pregnancy, medical examinations, including pregnancy tests and ultrasounds, are essential. These evaluations can provide clear evidence of the presence or absence of an actual pregnancy.

We’re Here to Help You Identify Signs of Pregnancy after IVF

As you navigate your IVF treatment, it's important to remember that it’s normal to experience a range of emotions and expectations. CARS is here to provide you with the support and understanding you need throughout your journey to parenthood.

Remember that we're here for you, every step of the way, knowing that the ups and downs can be challenging. We encourage you to schedule a one-on-one consultation with one of our fertility specialists to learn more about the journey and how we can help you realize your dream of starting or growing your family, providing you with the care and support you need.

Pregnancy Week by Week

A full-term pregnancy lasts around 40 weeks and consists of three trimesters—which begin on the first day of your last menstrual period. Each trimester develops the fetus using specific developmental milestones, and throughout this time, the pregnant person will experience varying side effects and changes in their body.

Although 40 weeks is the standard timeframe, a full-term baby can be born as early as 37 weeks and as late as 42 weeks. We believe it is important to understand how each pregnancy differs—and what soon-to-be parents can generally expect as their baby develops.

Helping you build your family is our only goal. We’re here to help you know which symptoms you may experience throughout your experience, week by week.

First Trimester (1-12 Weeks)

The first trimester is a crucial time for the development of the fetus. Over the first 12 weeks (about 3 months) of the pregnancy, the fetus will begin to develop major organs and structures, form fingers to toes, and weigh around one ounce. During this time, the eyelids will also form and remain closed until around week 28 (second trimester).

During the first trimester, the pregnant person will begin to exhibit changes that will likely last throughout the remainder of the pregnancy. These include:

• Fatigue and mood changes
• Food cravings and aversions
• Headaches, indigestion, and constipation
• Nausea and increased urination

Morning sickness can last throughout additional trimesters, although this symptom typically doesn’t last throughout the pregnancy and is most common during the first trimester.

Second Trimester (13-28 Weeks)

The thirteenth week of pregnancy marks the beginning of the second trimester. The fetus undergoes many changes during these fifteen weeks, marking a significant time for fetal development. By the end of the second trimester, the fetus will:

• Form skin, hair, and nails
• Form lungs, but the lungs do not yet work
• Regularly sleeps and wakes
• Develop the first bowel movement in the intestines

Other changes in the fetus include taste buds forming, bone marrow making blood cells, and fine hair covering the body. While the fetus develops, the pregnant person will experience several new changes, such as possibly feeling the baby move and the abdomen expanding as the fetus grows.

Additionally, darker areolas, potential swelling of ankles, fingers, and the face, itching, as well as more prominent stretch marks around the abdomen, thighs, breasts, and buttocks are common. Some may also notice dark patches on the face.

Third Trimester (29-40 Weeks)

The third trimester will last from the 29th week to the delivery, typically around week 40. (Remember—this will vary for every pregnancy.) Because this is the final trimester with the fetus, the pregnant person can expect most organs and body systems to have formed, paving the way for growth with each passing week.

For the fetus, the third trimester experiences several key developmental milestones. This includes the bones hardening, the eyes opening and sensing light, the complete formation of lungs, and the development of a vernix, a white, waxy coat over the skin. As delivery approaches, the fetus will also drop lower in the abdomen, usually facing head-down.

Pregnant people are likely to experience new discomforts and changes during this time, such as:

• Heartburn, shortness of breath, and frequent urination
• Insomnia and mood changes
• Nipple and breast changes
• Contractions, which indicate labor

Do I Need IVF?

In vitro fertilization (IVF) is a widely recognized and highly effective fertility treatment that has helped countless individuals and couples achieve their dream of parenthood. This advanced procedure involves the fertilization of an egg outside the body and the subsequent transfer of the resulting embryo into the uterus for hopeful implantation.

The Center for Advanced Reproductive Services (CARS) understands that the journey to conception can be filled with emotional and physical challenges. If you’re wondering whether IVF is right for your family-growing goals, our empathetic approach to fertility care will guide you through every step of the process.

When to Consider IVF

Deciding whether IVF is the right choice for you can feel overwhelming. This decision may be influenced by several factors, like specific infertility challenges, medical history, goals, or the unique needs of LGTBQ+ individuals and couples.

Determining the best course of action begins with knowing what to look for:

Unsuccessful with Other Treatments

If you've tried other fertility treatments—medications, intrauterine insemination (IUI), or lifestyle changes—without success, IVF may be worth considering. IVF may have higher success rates, as it can identify and correct several factors contributing to infertility at the same time.

The Center is proud to carry a 79.5% success rate for new patients age 35 or younger—which was 15% higher than the 2021 national average, according to the 2021 SART outcomes report.*

Age-Related Infertility

A woman’s fertility declines with age, especially after turning 35. If you are in this age bracket and have been unable to conceive, ovulation induction (OI) helps stimulate the ovaries to maximize egg production.

The quality of a woman's eggs also declines with age, which can result in failed implantation, miscarriages and birth defects. IVF with PGT allows for testing of the embryos for chromosomal abnormalities that may be a result of the age of the eggs.

Male Factor Infertility

Infertility can affect both men and women. In cases where low sperm health is identified, IVF and intracytoplasmic sperm injection (ICSI) can facilitate fertilization by directly injecting a single sperm into an egg.

Blocked or Damaged Fallopian Tubes

With blocked or damaged fallopian tubes, natural fertilization is unlikely to occur. There are several ways to diagnose this, including an X-ray test (a hysterosalpingogram), an ultrasound test (a sonohysterogram), or minimally invasive surgery (laparoscopy).

IVF bypasses the fallopian tubes entirely by retrieving eggs directly from the ovaries and fertilizing them in the laboratory. Since IVF bypasses the fallopian tubes, it can also be a viable option for women who have undergone tubal ligation previously and who now want to grow their family. For many, IVF can be a more effective option than tubal ligation reversal procedures.

Endometriosis or Other Medical Conditions

Endometriosis, which is when tissue similar the lining of the uterus grows outside the uterus, is one condition that can impact fertility. Other medical conditions, such as ovulation disorders, including polycystic ovary syndrome (PCOS), hyperthyroidism, uterine polyps, and ovarian sufficiency can also impact the likelihood of fertility.

IVF treatment can increase the chance of conception through egg retrieval and a controlled environment for embryos.

Unexplained Infertility

For some patients, despite all the testing that is performed, there may be no specific reason identified that would cause infertility. In these cases, IVF can be a good option, as fertilization and early embryo development happen under controlled conditions.

Plan Your Family at CARS

Knowing if or when IVF might be appropriate can help you make an informed choice for your fertility treatment. During your time at CARS, you’ll receive the utmost care, support, and expertise to help you find a solution to any infertility challenges you may be facing.

How Early Can You Take a Pregnancy Test?

Taking a pregnancy test too early after fertility treatment or testing can provide inaccurate results. By accurately determining the right time to take a pregnancy test, individuals or couples who undergo treatments like IUI (intrauterine insemination) or IVF (in vitro fertilization) can help reduce stress as you work toward building or growing your family.

The wait to learn if you’re pregnant after completing fertility treatment (either IUI or an IVF embryo transfer) is commonly known as the “two-week wait” and with it can come exhaustion, frustration, and anxiety.

We know it can be very difficult to resist taking a test early. At The Center for Advanced Reproductive Services (CARS), we recommend waiting for the proper timeframe to ensure accurate results. Our team of counselors is here to provide additional support during this time.

Read on to learn more about the factors that impact when you can take a pregnancy test.

Pregnancy Testing for Fertility Patients

If you’ve undergone fertility treatments, or if you’re considering them, it’s important to know that the timing of taking a pregnancy test follows a more complex timeline. Both IUI and IVF can impact the timing of ovulation and implantation, which affects when hCG (human chorionic gonadotropin) levels are detected.

Our fertility clinic closely monitors hCG levels through blood tests, which are generally more sensitive and accurate than standard home pregnancy tests. This enhanced accuracy better tracks any changes in hCG levels to provide more reliable results.

We recommend professional testing, including pregnancy tests, for anyone who has undergone fertility treatments. This helps to avoid any inaccurate results.

Importance of Tracking Ovulation for Successful Conception

Understanding the timing of ovulation is critical for accurately predicting the best time to take a pregnancy test and increasing your chances of conception. Typically, ovulation occurs about 14 days before the start of your next menstrual cycle. During this period, your body releases an egg from the ovary, which is then ready for fertilization.

Tracking your ovulation can provide valuable insights into your most fertile days. By using tools such as ovulation predictor kits, monitoring your basal body temperature, or observing changes in cervical mucus, you can identify when you are most likely to conceive.

After ovulation, the fertilization process begins when the sperm and egg travel through the fallopian tubes, leading to implantation. This process usually starts about 6 to 12 days after ovulation. It’s during this time that your body begins producing hCG, the hormone detected by pregnancy tests.

Once hCG levels are sufficiently high, it’s time to take a pregnancy test. For the most accurate results, follow the instructions provided by your fertility specialist. Their guidance will help ensure that you’re testing at the optimal time for detecting pregnancy.

The Right Pregnancy Test Matters

For the most accurate results, it's generally best to wait until after a missed period to take a pregnancy test. This timing allows hCG levels to build up enough to be detected reliably. While some individuals may take a test just 10 days after ovulation begins, your fertility specialist will provide specific guidance on the best time for you to perform a pregnancy test.

For those undergoing fertility treatments, the timing and type of pregnancy test are especially important. Over-the-counter pregnancy tests aren't always reliable for fertility patients due to factors such as lower hCG levels in the early stages. This can result in false negatives, which can be disheartening and misleading.

By relying on clinical pregnancy tests, you can better ensure accurate results that detect the presence of hCG. If you have any questions about what this process may entail, schedule a consultation to learn more.

Start Your Journey to Parenthood

While it may be tempting to take a pregnancy test as early as possible, waiting until after a missed period can save any potential disappointment with a false negative. For those trying to conceive, we invite you to learn more about your options with our fertility specialists.

Pregnancy is a different experience for everyone. CARS believes in providing everyone with the information needed to make an informed decision as you decide your path to parenthood. Schedule your first consultation with our fertility specialists today.
