Brandi • My name is Brandi and my fiancé`s name is Joe. I`m 23 he`s 25. TTC baby #1. I`m a hair stylist and he`s in flooring.
So I'm gunna post here because it's the only place I really get answers. I just started tracking my BBT yesterday.. How much should I expect it to fluctuate normally when I'm not ovulating?
