28 days of blastocyst transfer is equivalent to about 47 days of pregnancy. The length of pregnancy varies depending on the type of embryo transferred at the time of the blastocyst transfer, in the case of a day 5 blastocyst transfer, 28 days of blastocyst transfer is 28+19, therefore around 47 days of pregnancy. There will also be some difference in the length of pregnancy when choosing different types of blastocyst transfer, but there is usually no significant difference. If you have had a blastocyst transfer, you need to do your usual job of keeping the pregnancy alive, avoiding exercise as much as possible, and you can get plenty of rest and ensure adequate nutrition. If vaginal bleeding, abdominal pain and other phenomena occur in the process of pregnancy, you need to consult a doctor in time.
