1st time TTC


I came off the pill 3 weeks ago. This is my first time TTC. I've never paid this close attention to my body, but now I am and I'm noticing a lot. I'm confused by BBT, I've heard SO many different things about what it means. I did OPK on 1/9, it was negative. OPK yesturday and today said hi, but not peak. So I have no clue if I've O'd or not. Though 3 days ago I had all the symptoms. Here's the temps I've entered. Glow think I'm O'ing today. Thoughts would be appreciated.
