Ok, I'm at 10 dpo and super depressed! I'm having cramping, just like those I experience when AF is coming. For the past 3 days my OPKs have been positive at 2 pm. Today the OPK was negative and HPT got a BFN. I have had a bit of nausea and am now taking phenergan for it. Yesterday, I had mild cramping and twinges on my sides. Now I'm cramping like AF is coming. In the past, I've gotten pregnant by having sex only once during my week ov ovulation - and that was when I didn't use OPKs - I just estimated. Anyone else experience cramping and still preggers or a BFN at 10dpo but were actually pregnant?
