It is not easy for families to assist with IVF, especially after egg retrieval and fertilization and embryo transfer, they are worried about the number of embryos formed and whether the embryo transfer is implanted. So, how long can the pregnancy test be done after IVF transplantation? How long can the fetal heart rate be tested after the pregnancy test is successful? Here is the introduction of Baomei from Aibaolai.
1. How long can I get a pregnancy test after IVF transfer?
After IVF embryo transfer, it usually needs to be free in the uterine cavity for three to four days to find the best implantation point, embryo implantation, clinical pregnancy, but Since each patient's physique is different, the quality of the embryos implanted is also different, so the embryo implantation will also be affected by individual differences, resulting in different implantation time, which will allow some patients to implant earlier Some, and some patients implantation is relatively late. It is usually better for patients to take blood to the hospital for pregnancy test 14 days after embryo transfer.
2. How long can the fetal heart rate be measured after the pregnancy test is successful?
After the IVF embryo transfer, a blood test will be performed on 14 days. After the pregnancy test is successful, the main reason is to be able to hear the baby's fetal heartbeat.
However, the development of embryos has a certain pattern. In the embryo laboratory, after 24 hours of in vitro fertilization, the eggs and sperm divide into 2 cells, and on the third day of fertilization they become 16 cells. Many hospitals will choose to perform transplantation at this time, and some hospitals will choose to transplant on the 5th or 6th day. The embryo becomes a blastocyst after the fifth day of development. At this time, it contains 50 to 100 cells and begins to differentiate into two different groups of cells, the trophoblast and the inner cell group. The trophoblast will develop into the placenta, and the inner cell mass will develop into the fetus.
After IVF embryo transfer, they begin to implant in the uterus and grow up. About 28 days after fertilization, the embryo began to differentiate its organs, and the most primitive heart tube appeared. The original heart tube is the early stage of the heart, and it will slowly develop into a heart with four cavities, but at this time it is still an official cavity, but there is already blood flowing in the blood vessels, and the small heart begins to beat. Therefore, the expert doctor recommends that the fetal heart rate be measured 30 days after the embryo transfer, which is 18 days after the successful pregnancy test. Z1z
's warm reminder from Aibaolai's Baomei: Whether waiting for a pregnancy test or waiting for a fetal heart rate after an embryo transfer, we need to maintain a normal mind and not be too nervous. This will have an impact on the implantation and development of the embryo.
