How Many Days After a Frozen Embryo Transfer Can You Test?

When you test for pregnancy after your frozen embryo transfer depends on when the transfer took place. Here’s a look at the recommended timeframes.

The frozen embryo transfer (FET) is a big step in your IVF and surrogacy journey. Once the transfer is complete, you might be eager to test as soon as a pregnancy is detectable.

The answer ultimately lies with your fertility clinic and when they schedule you for a blood pregnancy test, but if you want to test at home before then, we have you covered.

Fill out our form online to learn more about your questions surrounding when to test after the FET. That could look like helping you complete your surrogate planning questionnaire before your embryos are created or recommending reputable fertility clinics for you to choose where you’ll create these embryos. We’re here for each step of your journey.

How Many Days After Embryo Transfer Can You Test?

Most fertility clinics recommend that you wait two weeks after your FET to test for a pregnancy. The reasoning behind this length comes from ensuring the most accurate results.

An early pregnancy, for example, may result in a false negative because your body is not producing enough of the pregnancy hormone, human chorionic gonadotropin (hCG) to be detected by an at-home pregnancy test.

Testing before the recommended wait time is an opportunity for false positive and negative pregnancy tests, unnecessarily throwing your emotions in disarray.

How Many Days After Frozen Embryo Transfer Can I Test? – 3 Day Transfer

Depending on when your FET took place, it’s possible to test for pregnancy as early as nine days after a day three transfer.

Embryo development takes place in the first four days before the embryo implants on the endometrium between the fifth and seventh days.

By the ninth day, hCG levels could be high enough for a pregnancy test to detect a pregnancy.

How Many Days After Frozen Embryo Transfer Can I Test? – 5 Day Transfer

If the FET took place at the blastocyst stage, it’s possible to test for a pregnancy as early as seven days.

Because day 5 embryos are more developed, apposition, adhesion and invasion of the embryo occur 3-5 days after the embryo transfer..

  • Apposition

    The blastocyst lands near the uterine wall and forms an initial, but loose connection.

  • Adhesion

    The embryo attaches to the endometrium.

  • Invasion

    The outer cells of the blastocyst penetrate the uterine wall.

The seventh day is when hCG levels could be high enough to detect a pregnancy.

Why Is There a Wait for How Many Days After the Embryo Transfer You Can Test?

In addition to ensuring accuracy when a pregnancy test is taken, the wait times after a FET, no matter if it’s a day three, five or seven embryo, exist because it allows the embryos time to develop.

More accurate pregnancy test results come after allowing hCG to be released into your bloodstream as the embryo’s development continues.

There are two ways for you to test for a pregnancy once you have met the wait time, a blood test with your fertility clinic or an at-home pregnancy test.

Although both tests monitor hCG levels, a blood test at your fertility clinic is much more accurate, as it measures the quantitative level of hCG. An at-home pregnancy test may display a false negative of hCG levels.

Waiting to test for pregnancy can bring a whirlwind of emotions and whether you need help addressing those emotions, or want to talk to other surrogates that have gone through the process themselves, we’re here for you.
