Calling chart pros!

This is my third month charting (but last month was pointless because I didn’t temp before O), and the first time I got pregnant. My temps were erratic during my FP (I wake up for work between 5-6:30), but it does look like a temp shift. Does it look correct? I do feel like I O’d on CD 15. I’d feel like it would be more cut-and-dried if my coverline didn’t have so many temp spikes.

I’d love another set of eyes and opinions.

Thanks!!
