How do you find out if you are pregnant? For most treatments, doctors will wait till you miss your period before starting pregnancy testing. Ask your doctor when you should schedule a pregnancy test every time you take treatment — after all, you never know when it’s going to work! A reasonable choice would be to conduct the test 16 to 18 days after ovulation. For IVF and GIFT cycles, in some clinics, testing may start as early as 10 to 12 days after the embryo transfer or GIFT.
A pregnancy should be documented as early as possible. This is important, because appropriate care and precautions can then be taken at an early stage. The most sensitive pregnancy test is a blood test for the presence of beta HCG (human chorionic gonadotropin). The HCG is produced by the embryo, and serves as the embryo’s signal to the mother that pregnancy has occurred.
