i had a physical intercourse with my girlfriend 3-4 days back but i did not insert my penis completely because it was painful for her. But i did try to insert. During that time i had an orgasm. but did my semen go inside her vagina or not i am not sure therefore i told her to take i-pill that day itself. Now the thing is that there is a bleeding in her vaginal part after 3-4 days of intercourse. So does that mean she is pregnant ?
