My temps do that too, with going up during AF, not sure why, but I'm not worried about it.
I do agree with Jennifer about your LP being under 10 days consistently. Let us know what the dr says. If your dr doesn't believe you or gives you a hard time, then I would find another dr. You definitely don't want a dr that you are not comfortable with during a pregnancy and hey, we pay them, so I'm a strong believer in taking control of your own healthcare.

Good luck and keep us updated!
