Hi, yesterday morning my boyfrnd ejaculated thrice near my vagina area. I am not sure whether any part of ejaculation went inside my vagina. I took postpone 72 within 24 hours. My period was supposed to come on 3rd June. We had sex on 2nd June. Is there a probability to get pregnant. If there is no exchange happened will it be known. If i am not pregnant within how many day I should get my periods. The biggest mistake was we never knew that there is probability to be pregnant when ejaculation happens near vagina area. Our understanding was insertion of penis inside vagina would only cause pregnancy.
