Ovary pain 5dpo

Hello, looking for some advice as I am 5 dpo (ovulation confirmed with Clear blue digital opk) and I am having a lot of soreness on my left ovary right behind my hip bone. I’ve been reading it could be the corpus luteum releasing progesterone but I’m wondering if anyone else has had this and ended up NOT being pregnant? I usually have little twinges right before I ovulate but not after. I’ve been ttc for 2 years and a little over a month ago was diagnosed with pcos and started metformin. Any personal experience greatly appreciated :)
