Did I ovulate cd 12 or 13?

Hi everyone. I took letrozole cd 3-7, went in for a scan on cd 12, had a 24mm follicle and we triggered that day. I know you usually ovulate 36 hours after the trigger but do you think I ovulated Friday? I did wake up yesterday and today around 4:30, rolled over and went back to sleep then tempted at 6. Do you think that wake up would cause a false elevation? Just wondering when to start my progesterone as I’m supposed to start 2 days after ovulation 🙃
