The days waiting to find out if you have become pregnant after in vitro fertilization (IVF) can feel very long indeed. A pregnancy test should be able to determine accurately whether the transferred embryo has implanted within 10 to 14 days of the procedure. Testing earlier may provide false positive results, as the pregnancy may not be valid or there may be the residue of fertility drugs, such as human chorionic gonadotropin (hCG). After embryo transfer, you will need to wait 10 to 14 days before taking a pregnancy test to determine if you are pregnant.

Have a doctor perform a blood serum hCG test 10 to 14 days after your transfer. This test is called a beta. A blood test may be qualitative or quantitative, giving a measurement of the hCG in your blood. With IVF and fertility protocol patients, it is very common for several betas to be drawn, at least 48 hours apart--beta number should double roughly every 48 to 72 hours.

Take a home pregnancy test at least 10 days after you have taken any hCG injections. hCG injections will give a false positive on a home pregnancy test if the test is performed too early. These shots are a normal part of IVF protocol.

Continue to have your hCG levels monitored. A late menstrual cycle may simply mean a chemical pregnancy or miscarriage. Beta levels of hCG should double roughly every 48 to 72 hours. Levels that do not double may indicate that the pregnancy is not going to continue.
