I had unprotected sexual intercourse with my girlfriend one and a half months ago. She had I pill.. The next day again we had intercourse but with condoms. After 10days of having last sexual intercourse she got her periods. It was heavy bleeding for 5days.we didnot have any sexual encounter after that. Now this month she got her periods a bit late and it is very light. Is there a chance she is
pregnant? Is the light bleeding due to pregnancy?
