How Long After Intercourse Can I Take a Pregnancy Test?

by Anne Sommers, Licensed Midwife | October 25, 2000 12:00 AM

I am just starting to try and get pregnant-how soon after intercourse will home pregnancy tests work?

Approximately four days after fertilization, the egg will start to produce a pregnancy hormone called human chorionic gonadotropin (hGC). A pregnancy test will detect this hormone about one week after fertilization.

Most women tend to wait to take a pregnancy test until after they have missed one menstrual period. If you take a pregnancy test one week after you were supposed to get your period, the result will be about 95% accurate. If you take it too soon after fertilization, it may show up negative when in fact you really are pregnant

Pregnancy test are meant to be considered screening tests. If your test comes up negative, but you are experiencing symptoms of pregnancy you should call your doctor. If it does come up positive you should call your doctor and set up an appointment for your first prenatal visit.

I had unprotected sex on halloween night. i was on my period at the time and i thought i would be fine. it turns out that you can still get pregnant like that. on the 9th (4 days ago) i was spotting and i thought it was my period starting, but it was way too early to have my period again. there was just a little but of blood and that was it. i'm wondering when can i take a test? tomorrow will be 2 weeks since halloween.
