hi stephen, i have been having unprotected sex with my boyfriend for a couple of months bt he doesnt pour inside me, he does the withdrawal method. 6 days ago, we had unprotected sex and he poured inside me 3 times dt same day, the next day, i took postinor 2 which is about four days ago now. and now am two days late on my period. could i be pregnant or could it be an effect of the postinor 2? thank you!
