According to this app, I ovulated on the 17th and I figured it was accurate because my CM was very stretchy and snotty looking. (Yes I know CM is not always accurate). After the 17th, my CM was back to normal, not very much of it and not stretchy at all. On the 20th, I had A LOT of CM and it was very very stretchy and snotty. So I thought, what the heck?? I took 2 ovulation tests last night and they were positive and 1 this morning about 11 and it was VERY positive. I’m 9 days away from my period...I didn’t think you could ovulate that close to your period?? I’m new to the <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> so please help lol
