Could I ovulate sooner than what Glow is predicting?

Alexis

Based on the app, I’m 4DPO, but I’m starting to think that maybe I ovulated sooner. I’m nauseous, like, even talking makes me gag. I’m having aches in my hips that radiate from front to back. HOT FLASHES and very slippery/stretchy discharge. And my belly is starting to look a little bloated... HELP!
