My bf fingered me on january and don't know if he had cum on his hand. i got my perdiod last month and this month but i don't know if i am pregnant.

Had periods already?: If a woman has her NORMAL regular menstrual period, she is presumed not pregnant. If she thinks she is pregnant, then doing a urine pregnancy test the week after missing her "normal" period, the week after getting a "strange or abnormal period," or 3 weeks after having sex, should give an accurate result. The pregnancy test needs to be done correctly and read correctly.
