GriffsKat - I had the same thing last cycle. My temps stayed above my previous coverline for about a week and a half after AF showed up. I had an initial drop but then they went back up. I kept testing thinking that I must be pregnant and I kept getting BFN. Not sure why. I think it was a hormonal thing since I was having issues with spotting and stuff but it was strange since my previous cycles were normal with low temps once AF showed up. Not sure but in the end, I actually got pregnant this cycle with the high temps after AF. Not sure but I do think it was hormonal and my body getting back into the swing of things after my dd was born.
