Has anyone ever experienced what started as spotting then turned into a light flow around 10dpo-13dpo and got a bfp? I started spotting/bleeding 1/21 but Af isnt due till 1/27, I am VERY regular and have a 30 day cycle. I tested this evening (did not wait the recommended 4 hours) and got a bfn. If its Af it is an unusual one as a only cramped a few hours, and have been in an oddly wonderful mood. I have a few other symptoms like weird head aches, bloating and dizziness that come and go.
