Wtf is going on

Mercedes

So my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> said as of today I'm in the middle of my ovulation. So I'm filling today out with all the exciting stuff going on in my life and then after I submitted it went back into my home page and now it says I'm two days past my ovulation day?? I don't no what's going on but I'm not about it. I'm so confused? Has this happened to anyone before?
