Okay so my DH & I BD'd a few days before and after ov. Starting from 6 dpo up until now (12 dpo) I've been having dull cramps. Last night the cramps got bad and when I used the bathroom and wiped there was light pink blood so I was sure af was starting but nothing else happened all night, the cramps stopped and there was no more blood. I took a test this morning and got a bfn. I still have two days before af is expected but I kind of feel like I'm out. Has this happened to anyone else?
