The 6 day blastocysts can usually be laid in about 3 days. There are usually no uncomfortable symptoms after the embryo is laid, and a few people may experience some discomfort, such as possible breast tenderness and a little soreness in the lower abdomen. Blood tests for human chorionic gonadotropin can be taken about 10 days after the transfer to determine if the transfer is successful. After the embryo transfer, the embryo will wander around the uterus for a relatively short period of time, but there is a chance of ectopic pregnancy. If you experience severe stomach pain or vaginal bleeding during early pregnancy, you need to go to the hospital for a timely checkup to rule out ectopic pregnancy. After pregnancy is confirmed, pay attention to rest, no strenuous exercise, keep your bowels open and do not have sex for three months.
