Me and my fiancé have been having sex for 3 years now. We never use condoms and I don't take birth control. But he does the pull out method every time. My periods come around the same time each month not the exact date but around it rarely it will switch from being the beginning to the end that's only happened once to me tho. I have my period all 7 days but my period isn't how it use to be. I used to have all 7 days of bleeding but not its 3 days and then I stop for one and the rest of my days is not as heavy, I use tampons but at night I use pads. And I haven't got pregnant at all. Lately we have been talking about starting a family after we get married, of course. I'm worried that my body won't let me get pregnant because threw out 3 years I haven't got pregnant.
