Is anyone else’s glow doing this? Help!

❤ Sarah ❤

So by glows predictions I was supposed to ovulate on the 16th, I ovulate late and always have so idk why glow even predicts my ovulation in the normal range of most women. I got my positive opk today and even used the analyzer on here and it said positive. Glow still has that ovulated on the 16th when the test was negative. I’m actually starting to get frustrated. Anyone else?
