Ovulation Results/Help with App

I have been <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> for 2 months. Last month I didn’t fully capture my LH surge, just BD as soon as it was high & continued for 2 days.

This month, I’m trying to be more consistent. My highest results were 2/12 and 2/13, and I had ovulation pain at the same time. However, once I enter my ovulation tests the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a>, my ovulation date keeps getting pushed back - now says 2/16 and previously estimated 2/13. I feel like I already ovulated as I had mild right side pelvic pain, which is normal for me.

Is it normal for ovulation tests to not get as dark as or darker than the control line? Do you think I ovulated already? I’m very confused. Any advice or help welcome! We did a lot of BD this weekend so 🤞
