Ovulation pain after baby

Kw

I’ve never had pain when ovulating, and during periods my pain was always in my lower back, never front cramps. Well I had my first baby a year ago and got period back 6months ago. The last 3 cycles, I’ve had bad pain during ovulation. It’s all day pain and is bad during sex and carrying heavy stuff. But only during ovulation week. Is this normal? Any chance it is a ovarian cyst? I have a generally high pain tolerance and this sucks haha
