Hey y'all. So I've been charting for 11 months now and I've never had this before and I'm wondering if anyone has any insight. I temp vaginally due to erratic temps orally. So during AF I temp on the potty even though you aren't supposed to. I figure if I do it every time it'll still show some consistency and I expect it to be a little higher. However the last 3 days it has continued to go up and today it's in the range of my mid-range Post ovulation temps.

I regularly ovulate CD 16 and after so I'm certain this is not early ovulation. I had pretty heavy flow for 2 days and a temp drop at the time I expected AF, but now it's high again.

Anybody ever experienced this or have a clue?
