Hi people... I'm actually a guy that want's to ask a question as I know you'll be able to help. Me and my girlfriend had unprotected sex on the 7th of July however she got her period the next week. Can we trust the period that she is not pregnant? How soon will her period stop,immediately? I did not cum inside of her and she is not on birth control pills. Believe me this will not happen again as this stress is not nice. Is there any way she could be pregnant or can I relax?
