I apologize in advance if these are silly questions. I think I know but then I second guess myself. For the last 3 months I have just been using babymed's Ovualtion cal. with the calendar. I have been basing it off a regualr "28 day cycle" Each month I have been getting AF 2-3 days before it says. So based off of that, would it mean my cycle's are 25/26 day cycle? Because I am getting AF a few days eariler? So in that case.. I would be Ovulating 2 to 3 days eariler than it says as well? Or is that not how you base how many days your cyles are? Thank you !!!
