Newbie and need insight!

Heather • Mon, Sep 26

Hi! This is mine and my husband's first month TTC. I'm new to all of this and was wondering how my chart was looking so far? I read online that my BBT's shouldn't vary more than 0.5 degrees, but was wondering how true that was based on yall's experiences? I know this isn't a whole month and that I'm just entering my fertile week! I started taking OPKs after my period because I wasn't positive when I ovulated during my cycle. All have been negative so far, but one looked close to positive a few days ago and then they lightened up. I read this is normal?

Thanks for your help!
