Can you take a pregnancy test while on your period and it still be right?

No, if a pregnancy test is taken and you get a result while you are on your period, your chances of getting an inaccurate result may be higher. Your menstrual cycle causes you to shed blood cells and uterine tissue. Therefore, the pregnancy test may get a distorted result of the menstrual blood if done while on your period.

A more accurate time for women to test for pregnancy typically is 1 week following the earliest your next period was expected in your menstruation cycle.
