Just a thought/comment.. about me getting pregnant

So what I am thinking about is how did I not get pregnant when I was with the (4)men before my now fiance of years. This was between age 16 when I lost my virginity and around 21 when I met my fiance. I didn't use protection with them, but I wasn't with each of them that long either. The one I was with for about 8 months always pulled out. So this could maybe explain why but I still in theory could have gotten pregnant. I was so nieve and young and thought maybe I couldn't or wouldn't get pregnant lol thankgod it didn't happen with one of the men from my younger years. Anyway, when I met my fiance after about 4 months of dating I jokingly told him when i was in the (mood/moment) to get me pregnant and he said you want one I'll give u one. I laughed and said I never get pregnant and u won't get me pregnant either. Well well period never came and I peed on a stick and I was pregnant. So my point or thought on this story is- that maybe it's the guy that a girl is with that will determin wether or not she gets pregnant. If someone has been trying for years and years with the same guy maybe the girl needs a different man to do the trick. I get u love who u love or ur married to whomever ur married and truw love is what mattes. Thankgod i fell in love with my man(nowFiance) hard and quick and he was the one who got me pregnant. He had the special touch and still does... just a thought.... made me smile thinking back to this time when we first met
