Me and my fiance recently had unprotected intercourse and I'm not on birth control. I was on depo from.aug 2010 til aug 2012 and I switched to the pill. I've been off the pill for about a month. I haven't had my period yet but this happened 2 days ago. While Iwas on the pill Ihad my periods at the end of the month and now that I'm off idk when ill have my periods so what's my chance of becoming prego?
