When pregnancy is carried out through IVF, the body does not show the typical reactions of a successful transfer after the embryo transfer, and it is not possible to judge whether the transfer has been successful or not by the body’s symptoms. As long as there is no significant vaginal bleeding after the transfer, there is a possibility of success. Therefore, blood tests need to be performed more than two weeks after the embryo transfer, and the main purpose of the test is to find out whether the human chorionic gonadotropin in the body is significantly elevated. As long as the human chorionic gonadotropin is significantly elevated, the likelihood of conception is very high. An ultrasound is also needed at least three weeks after the implantation to check the condition of the pregnancy sac in the uterus to confirm the success of conception.
