Hi, I have PCOS, get my period each month but there is always a few days or a day in the difference each month. I'm using the premom app and Ovia to track everything. However, I am confused about high and peak ovulation days and am looking for some clarity on how to know which days are the most fertile. Last month, I had a peak on CD 14 at 1.19, however, this month, I only have a high today, CD 18 at 0.96. I have been looking online but to be honest, I can't seem to get my head around all the information. Any advice/info would be really appreciated. Thanks in advance
