Need a little help understanding these charts!

Sarah
So I'm pretty new to all of this, only in my first month of TTC. I've been taking my bbt every day and trying to check my CM and I'm pretty sure I ovulated on CD10 despite glow thinking it should be CD29. (I tracked my periods before coming off of BC and my periods were irregular which is why I think it thinks my cycle is so long! I was very regular before going on BC) Anyhow, I'm just wondering what your bbt is supposed to look like on your chart in an ideal world? I know it's supposed to go up to indicate ovulation but what does it do after that - both for pregnancy and if not successful? Any help would be gratefully appreciated. Thank you x
