Cyst? Late ovulation?

Rachael

I’m on cd 30, letrozole 5 mg this month, good follicles on day 12 predicted ovulation day was day 14. Pregnancy tests are negative and I’ve had spotting twice once the last two days (so probably period starting soon). However, I am having throbbing pain in my left ovary. Is this likely a cyst bursting? The big follicle was on my right but I had 3 follicles on my left.
