Question: how to tell if your pregnant after a few hours?
Answer: Pregnancy test (pee on a stick): 3 weeks Pee-on-a-stick (POAS) pregnancy tests detect pregnancy by the amount of hCG (human chorionic gonadotropin) hormone levels in your urine. This hormone is present (and begins growing) at the time of implantation, which is 6-12 days after ovulation.
