Looking at my past three months of charts, here's the deal:

Day 1-19, mid 97s.
Day 20-22, mid 98s.
Day 23-25 or 26: mid 97s.
Repeat.

Basically my temp is only in the 'high' range for about 3 days of the whole cycle.

So does it have to stay up in the high range? Mine doesn't wanna. Guess I'm just "cool". hah.

Maybe this is also do to with the copper IUD (I read that the IUD can affect when you ovulate (even though the cycle overall stays the same length, IUD apparently can make you ovulate later with a shorter LP). I am conflicted. I want to figure this out, but I don't want my IUD out yet as we are not ready to try. Sigh.
