Need help with OPK!!

RM

I’m new to OPK testing even though we’ve been TTC for a few years. I generally thought I knew when I was ovulating based on CM, glow prediction, and my ovarian pain but since that’s not been working, I started using OPKs.

But I’m confused because I’ve taken a test for the past 5-6 mornings (Day 12-17) and it’s been negative each time. I also didn’t have my pain this month but did have some CM changes. So does negative OPKs mean I didn’t ovulate this month or there’s something wrong with my ovulation? Should I keep testing?
