So this <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> says that I should be ovulating today... Just took an ovulation test and it came back completely negative, not even a vvfl line.. But yet, right around the time when my period was supposed to come (which was 3 days late) an ovulation test came up positive. I'm so confused with this and my body.
