OPK help

Rachel • TTC baby #1✨

I started <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> on the 28th. I missed 1 say which looks like I might have ovulated but I don’t know because I didn’t test. The app says I’m due to ovulate now, I’m feeling nauseous but my OPK is negative. I know it’s WAY WAY early to be taking a pregnancy test but I did because no self control 😂 my OPK’s seem to be getting darker again. Thoughts?
