About 7-10 days after the embryo transfer, the woman should take a blood pregnancy test to find out if she is pregnant. If embryo implantation has occurred, beta-hCG hormone will be detectable in the mother's blood at that time. This hormone is what we look for with a pregnancy test. In general, the hCG level doubles every 2-3 days in early pregnancy.
The first ultrasound scan is performed about 2 weeks later in order to confirm the presence of gestational sac and yolk sac.
