I was on the pill for about 6 months, and used depo three times before that, last shot in November 2015. Been off the pill since May of this year, and ovulated for the first time this month. We had sex the day I had the positive OPK and two days before that, about every other day since my period. Wondering how likely it is that I'm pregnant. AF due 12-24, I'm 4 DPO now and just having some light occasional cramping.
