left vs. right ovary. please comment if you have a similar problem.

Stella • lost baby #1 at 15 weeks May 2017. Pregnant with our rainbow baby!!😆💓due Sept. 2018

I've been charting for over a year now and have found out that my left ovary is dominant over my right. my left always ovulates on day 20-21. and my right is anywhere from 22-26 with pain and cramps a week before and after ovulation .. sometimes it's my left two times in a row, which I'm happy about. the one time I've gotten pregnant it's been from my left ovary. is this normal or is this a sign of pcos on my right ovary?
