My period hasn't came yet and I'm tryna figure out why ? .... my boyfriend and I had sex a few days before my period and it's still not on it's been 5 days now and idk what that means for certain . I've heard I couldn't be pregnant from it being only a few days but I know witch my second child it actually did happen that way except with my second child me and her father has sex 5 days before it was supposed to come and it never came and I found out I was having my little girl . So I want to know do think it's possible to happen that way when I was told it probably isn't something to worry about . ( i been cramping as if my period was about to come in for days now but then itll stop cramping and still nothing
