Unpretected sex and still no babies

Me and my boyfriend always have raw sex and he ejaculates in me more than once at a time. Sometimes we have sex multiple times a week/ month and I still get my period every month... I only came to this app to memorize when my periods come just in case I do become preganant or when to see when I'm Ovulating. Still not pregnant....(Btw I'm trying to become pregnant)
