Late ovulation 🤷🏼‍♀️

I was thinking I ovulated somewhere around cd10-12 as it was my highest reading but didn’t peak. This past week I’ve been having backache, slight cramps, twinges, nausea...thinking I was getting early symptoms around 9dpo. Well come to find out I got my peak last night/early this morning!? I’m shocked, I’m on cd20. I tested really late like 1145 pm after work, I’m hoping that wouldn’t matter and cause it to be making it too dark??? I usually test around 730. Should I still consider this my peak?

This is also my first cycle off birth control so I’m testing daily until af arrives as I’m trying to get a feel for my cycle. I’m glad I kept testing!! I almost stopped a few days ago but something told me to keep testing..we bd tonight!
