So last night at around 12 or 1 am in tha morning i had sex with my boyfriend and he usually cums in me. Well last night he did and 20 mins later i feel it cone out so i check myself and i can see red with it too. So im thinking im starting my period today and i checked This morning and yup i started. But is it likely that i can get pregnant since he had came in me right when my period was about to start?
