After the IVF transplant, the most anticipated thing is the "lottery", and after the successful pregnancy test, I began to silently look forward to the growth of the little life in the belly. Listening to the baby's careful beating of "poof, poof", let the pregnant mother feel happy.
After embryo transfer, how long does it take for fetal buds and fetal heartbeat to appear?
Post-transplant mothers-to-be generally go through these stages:
Blood tests for pregnancy are done around the 14th day after the transplant.
In general, a -hcg value of 7 iu l is considered infertile;>7IU L is considered pregnant.
However, a single blood value cannot accurately reflect the quality of embryonic viability, and it is necessary to retest at certain intervals to see how well it rises. In about 85% of normal pregnancies, blood values double every 48-72 hours.
Fetal heartbeat buds can be seen around 28-30 days after transplantation.
On the 28th-30th day after transplantation, expectant mothers can be examined by ultrasound to see if the gestational sac is in the uterine cavity and whether there is a fetal heart and fetal bud. If there is no fetal heart and fetal bud at this time, it means that the embryo does not develop well after implantation, and it needs to be observed for a few more days. If there is still no fetal heart and fetal bud, then uterine evacuation should be performed.
If the gestational sac is in utero and there is a fetal heartbeat, the reproductive doctor will adjust the fetal protection medication according to the blood value of the expectant mother to maximize the protection of embryonic development.
Embryo development is checked around the 42nd to 44th day after transfer.
Around the 42nd day after transplantation, ultrasound measured the size of the gestational sac and the length of the germ to determine whether the two grew simultaneously, and monitored the size of the yolk sac and the presence or absence of fetal heart beat. If germ growth does not match the number of weeks of gestation, ultrasound should be repeated after 7 to 14 days to assess the growth of the gestational sac and germ.
B ultrasound examination should pay attention to the screening of ectopic pregnancy, consider the possibility of simultaneous pregnancy inside and outside the uterus, and those with high suspicion of ectopic pregnancy need to be hospitalized for observation**. Some intrauterine pregnancies with ectopic pregnancy may not be definitively diagnosed in the early stages.
About 11-13 weeks of pregnancy NT, IVF graduation!
At this time, the implantation of the embryo has been relatively stable, and the placenta can provide the embryo with the nutrients needed for growth and development.
As long as the test tube has not graduated and the baby has not been born, the expectant mother should pay more attention to reduce external factors interfering with the growth and development of the fetal baby, and take care of the arrival of the baby wholeheartedly.
