If a guy cums in you a day befor you get your period, do you still get your period and be pregnant??

More likely that she CAN be pregnant jus to make sure get tested, when a girl gets her period is whn she's releasing an egg so if a Sperm fecundates (penetrates gets in side the egg) well u know she's pregnant. Jus get tested to be on the safe side, hope it helps and wish everything works for the best, add me if u like my advice and if helps vote thanks. I will be gladly to help any time
