Confusing

My <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> tells me af is due one 10-13 but another app tells me af is due 10-10. So my ov date was different on both I wanna test but don’t know what I should do. I don’t want to wait any longer ! I had taken a test yesterday and it looked like a vvvvvvfl but idk if I was seeing things. What should I do.
