So I was feeling super ovulation symptoms towards the end of sept like 26-10/12017. These symptoms were nausea and lower abdomen cramping. The app predicted my ovulation peak to be tonight. Here’s a pic of my opks, I threw one out from 10/1/17. Do you think I ovulated already? I didn’t have data to verify my current me for month of Aug but I miscalculated my cycle length I’m 99.9% sure. Any advice or help is greatly appreciated.
