Hi there my last day for my periods was on 13/01/20 today im bleeding it seems like periods but i dont know could it be that im pregnant i had sexual inter course on the 15 but we used protection.

Maybe not preg. but: It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a reliable result if done correctly. One can test about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. Having a regular menstrual period would mean "not pregnant."
