Annovulation periods vs periods when you ovulated

Hello ladies, I have a question. I have been ttc for 8 months now with no luck. I have started to wonder whether or not I'm ovulating 🤔 I get a period every month, however my cycles are always long. Usually I'll get my period a week after I'm supposed to, or even as long as 10 days late. I was on the pill for two years but stopped right before I started ttc. I think My periods are "normal" because I have pms, the bleeding starts light, gets heavy, then goes back to being light, and they last about a week. My question is that if I'm not ovulating but still bleeding, would that be different from a "real" period? Or does it sound like I'm ovulating late? 😕 I've tried finding answers on Google, but I can't find a clear answer. Please help, and thank you in advance xx
