I'm just curious. I want to ask that, can a girl who have not started their period able to get pregnant? my girlfriend is 16 and she haven't got her period or mentruation yet, can she possibly get pregnant if I have sex with her?
If a girl has not gotten her period then she cannot become pregnant. However, if she is to get her first period within the next month (which you don't know), then their is a possibility she will get pregnant. Use a condom, it's better to be safe than sorry.
