Pregnant? Probs not..

Hey, ladies.. I hope this is the right one to post this post.. But... My fiance and I arent trying to get pregnant.. But I have bad baby fever.. Lol. So. He came in me like two days ago.. And I just started my period. Shouldnt I have been like ovulating or something? And gotten pregnant? should I be concerned with my fertility(I read to wait a year of actually trying to go to the dr to see if its a fertility problem).. And again we arent trying to have a baby but if I got pregnant then it was meant to be you know? Lol!
