Could you become pregnant during your period? i had sex on the 4th day of my cycle and i think i have an average 27 to 28 day cycle.

Not likely: Technically, its not possible to get pregnant while on your period; however, this is not considered a reliable way to prevent pregnancy because sperm can hang around for 4-5 days after you have intercourse and ovulation might come early. So even though its unlikely, its best to assume you could pregnant anytime you have unprotected intercourse. Best wishes!
