so confused and down :(

<a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> saying this

yet ovulation strips saying this

first time I've tried testing. I usually just go by what the app tells me. I usually believed the app because that was my, um, hornier than usual week. is it still possible to be ovulating in the next few days even with extremely neg tests tonight?
