There is some variation in the number of days after embryo transfer, depending on the woman’s physical condition and the specific situation of the embryo, which needs to be analyzed on a case-by-case basis. Embryo transfer is an important part of assisted reproductive technology, including fresh embryo transfer and frozen embryo transfer. Usually, the fresh embryos will slowly implant 2-3 days after the transfer, and no later than 7 days. If the transfer is a day 3 frozen embryo, implantation usually occurs about 5 days after the transfer. If the embryo is a day 5-6 blastocyst, the embryo will usually come to bed 2-3 days after the transfer. Due to the differences in women’s body type, the time of implantation also varies and may be half a day earlier or later. After embryo transfer, it is recommended to rest in bed for the first 3 days, and after 3 days you can live normally. In addition, you should pay attention to nutritional support and keep your mood relaxed to help improve your chances of pregnancy.
