Calling all BBT trackers!!

Aimee • TTC #1
What do you normally hover around for pre/post and how long have you been TTC?
I just read that your BBT can reveal health problems. I seem to be on the low side of what they claim to a normal BBT for pre and post ovulation, but I've learned that every woman is so different!  I'm hoping to hear from you woman to get a sense of what "normal" is and if us with "abnormal" have been TTC longer.
