I think I'm out :'(
I'm 12dpo today, and after what I thought was a triphasic chart on FF, my temp dropped by 0.4 degrees. It's still above the cover line, but AF is due tomorrow. I was having temps above 99.0 for three or four days straight, and then it dropped to 98.8 (cover line is at 98.7) this morning. I was reading that some women still went on to get BFPs after a dip this late, but that your temps usually rise. I had three BFNs on 9dpo-11dpo. I really felt like this was my month!
Sorry for the pity party! Rant over!
