Any ideas on when I ovulated?

Hello,

I haven’t had any luck with opk’s. Doc said to just bbt this cycle. I still tested though just to see if something would pop up. The closest I got to a bfp was on CD17 but a few on here said I didn’t but was close. Well later that night and the next 2 days I tested and barely got a faint line. So I know my window was over. Even though I didn’t get a bfp on CD15 I’m thinking that’s when I O’ed. According to another chart I have to fill out for my doctor it automatically put I O’ed on CD15. I guess it thought my temp spiked enough for ovulation. Last month was also CD15. Could you please take a look and see what you think? Also, do my temps look ok or kinda all over? I haven’t slept well this past month so I wasn’t sure which temp to go with. Oh one more thing, I see glow finally gave me a cover line. How does that work? Thanks so much.

BFP on CD17. Yes or no? Darkest the line has ever gotten.
