Tested this morning on a frer and BFN. I will now count myself out as I am 13 dpo and af is due tomorrow. I have been SO exhausted, have had a headache as well. The spotting I had DEFINITELY seemed like IB to me, pink at first, then dark brown and it only lasted a day. I have never spotted like that before AF. BUT wouldnt a frer have picked up hcg by now? If that WAS IB it would have been 3 days ago, and I think I would have enough hcg by now for a frer to pick up. Has anyone else used a frer and gotten a bfn then went on to get a bfp a few days later? I still have a headache this morning, I was really hoping it was from a change in my hormones due to pregnancy. Oh well, I am sure af will be here tomorrow :/
