Yeah, your temps are still WAY above coverline. I don't think it means anything. During pregnancy, your temps will rise and fall.
Btw, my temp actually dipped below coverline the day before AF was due, but then it came back up above coverline the next two days. So far, so good! This is my 3rd day of missed AF.
And when searching pregnancy charts, I saw some that had that same pattern - a dip around AF. But again, yours is still well above coverline and doesn't look at all like the other cycles.
ETA: I didn't temp this morning, since I got a BFP yesterday and I've missed AF. Temping would probably drive me crazy at this point, so I'm stopping that all together.
