Ovulation cramping

Does anyone else get cramps a few days before ovulation? I’ve had cramps all day today. Yesterday it was slight cramping in my lower back but today it was definitely located on my right ovary. The reason I’m asking if anyone gets cramps BEFORE ovulation is because I am doing opk’s and temping and neither have shown that I’ve ovulated. This is supposed to be my fertile window with ovulation on the 22nd but I’m sometimes irregular due to PCOS :/ I need help lol. I just want to get pregnant!!😝
