ok, my girlfriend has been on her period for 5 days. tonight, she got off of her period. we were laying in the grass and had a little sex for about 3 minutes. when i felt myself about to cum i pulled out. we laid there for about a minute and i wiped the cum off of my penis with my shirt. after that we immediatly started to have sex again. im scared because i dont think i wiped all of the cum off of my penis. can she get pregnant the same night that she came off of her period? im freaking out because i didnt think about it before i stuck it back in. please help me by giving me good answers.
