Opk second guessing

Emily

I have 2 apps that "measure" the lines from the tests automatically. Glow says this is positive, another app says it's still negative. Normally, I would have no problem considering this my peak, but I'm second guessing it. I'll test again later this evening, but I'm wondering if anyone had any opinions about what they'd consider it. This was also taken within 10 minutes. Thanks!
