Not sure if I’m ovulating

ina • Sat, Sep 05

I been monitoring my bbt and my opk but I’m yet to see a high or a peak on my opk. Glow predicted I would ovulate tomorrow but due to my negative OPKs its been pushed to ovulation in another 4 day’s. I’m not sure whah is going on. Can anyone help me? I’ve attached my glow chart plus my FF chart. Thank you I’m advance
