You can expect to have a period 12-16 days after your embryo/blastocyst transfer if this is the case. Vaginal bleeding can also occur as the embryos/blastocysts try to implant in your womb. If you experience any bleeding you should contact us.

As ovulation draws near an ultrasound will be requested to measure the thickness and maturity of the endometrium. If this is suitable, the embryo transfer will be performed 2-3 days after ovulation.

Frozen blastocyst transfers should have hatching and the beginning of implantation by about 1-3 days after the FET. Early pregnancy detection following blastocyst transfer is possible with a sensitive blood assay for HCG hormone by about 9 days after a fresh or frozen blastocyst transfer.

Once you've conceived, the body begins to produce hCG as soon as a fertilized egg implants into the uterine wall, and it typically takes another 8 to 14 days before the hCG levels rise enough to be detected by an at-home pregnancy test.

If the embryo does in fact implant and begin to grow, hCG levels will rise and the line should get darker." hCG levels are abundantly present two to three days after your missed period (15 to 16 days after ovulation), so if you have a faint line, wait until after your missed period to test.

hCG can first be detected in a blood sample about 11 days after conception. Levels of hCG continue to double every 48 to 72 hours. They reach their peak around 8 to 11 weeks after conception. hCG levels then decline and level off, remaining steady for the rest of the pregnancy.

It takes a couple of days after implantation to have enough hcg for a positive pregnancy test. Good luck.

Implantation occurs on average, 9 days after ovulation (with a range of 6-12 days) or about 5 days before a missed period. hCG levels are detected in the blood as early as 2-3 days, and in the urine 3-4 days, after implantation.

What to Expect Day 1 to Day 3 After Embryo Transfer. After embryo transfer, you'll have to wait around 2 weeks before your pregnancy test. This might not seem like a long time, but if you've been trying to conceive for a while, 2 weeks can feel like 2 years.

After you conceive (when the sperm fertilises the egg), the developing placenta begins to produce and release hCG. It takes about 2 weeks for your hCG levels to be high enough to be detected in your urine using a home pregnancy test.

The takeaway. The 2-week wait after an embryo transfer is often filled with emotional, stressful, and exhausting ups and downs. Although some early signs such as light bleeding, spotting, and cramping could mean the procedure was a success, the only guaranteed way to determine if you're pregnant is a positive test.

By 7 days post ovulation a pregnant woman can have up to 50 mlU/ml of hCG circulating in her blood. So we can assume that most, but not all, pregnant women will have enough hCG in their system by 7-10 days after ovulation to confirm a pregnancy with a highly sensitive test (20 mlU/ml).

HCG Levels During Pregnancy HCG levels rise eight days after ovulation, peak at 60 to 90 days, and then lower slightly, leveling off for the remainder of the pregnancy. Typically, during the first 10 weeks of your pregnancy, HCG levels double every two days.

You need to wait to see if the embryo transfer was successful. While you may be pregnant, it can take up to two weeks for the placenta to begin producing enough hCG hormones for detection by a pregnancy test. After the embryo transfer, you may wait at the clinic for several hours before the doctor sends you home.
