My boyfriend and i had anal sex and he ejaculated in me.. should i be worried? ive been taking the pill for a little over a month to regulate my period but it still hasnt fully worked for that purpose. He ejaculated in my anus, but i had a tampon on and my period, i cleaned myself very well after, pushed the rest of the semen out, cleaned it.. and im also taking the pill... should i be worried about pregnancy??
