Once the transfer of the embryo to the uterus has taken place, it takes up to 9 days for the human chorionic gonadotrophin (HCG) to be high enough so that the pregnancy can be detected when doing a pregnancy test. However, most patients might be wondering, what happens after embryo transfer day by day? To ease your nerves, it’s therefore important to know what happens each day and know what takes place for the entire 9 days after an embryo transfer. After a successful embryo transfer, below is what happens each day.
Day 1: On the first day after an embryo transfer, the blastocyst begins to hatch and emerge from the cell, a process called hatching, and the cells will keep on dividing through this process.
Day 2: This is a crucial day because it’s when the embryo begins to attach itself to the uterine lining as the blastocyst continues to grow.
Day 3: On this day, the blastocyst attaches deeper into the uterine lining and implantation begin. It’s perfectly normal to experience some bleeding or spotting around this time and it’s not a cause for concern. Also, not all women will have spotting or bleeding when implantation is taking place.
Day 4: On the fourth day, the blastocyst continues to attach itself deeper into the uterus. Light bleeding or spotting may continue on this day as the embryo occupies the endometrial blood vessels to nourish itself through the maternal blood supply. However, in case you don’t bleed, get cramping, and spotting, it does not necessarily mean that implantation has not. Not every woman will experience that.
Day 5: During the fifth day after a successful embryo transfer, the implantation process is considered to be complete and the embryo is developing vigorously along with the cells that will eventually become the placenta.
Day 6: The growing embryo on this day triggers the release of human chorionic gonadotropin (HCG) into the bloodstream which will be picked up when doing a pregnancy test. This hormone as well triggers the increase of progesterone released in the first trimester to enrich the uterus lining and sustain the growing embryo or fetus.
Day 7: The fetal development is in full swing and the embryo continues to develop quickly. As the placenta begins to take shape, it continues to release more HCG into the bloodstream.
Day 8: There is more HCG being released in the blood on this day. The development of the fetus continues as the placenta also begins to function as required.
Day 9: By the time you reach the ninth day, the levels of the HCG hormone are high enough in the bloodstream to be detected by a pregnancy test kit. In case the test turns out to be negative, it’s advisable that you wait for another two days and repeat the test again since the levels of HCG will be high and more reliable to give an accurate result.
In addition, it’s essential that you know what happens after embryo transfer with the help of some symptoms. After an embryo transfer, you may experience cramping and pelvic pains, which can be a sign that the treatment was successful. Also, you may feel some fatigue and tiredness which can be a result of the pregnancy or even a side effect of the medications you’re taking. Some women will have very tender, sensitive, or sore breasts as an early sign of pregnancy as well as an increased need to pee. Having gone through IVF, it’s advisable that you know what to expect so that you prepare yourself well enough in case you experience anything.
