Yes, I was a regular 28 day cycle till my late 30s. One ovary is now on a 28 day cycle and the other is on a 23 day cycle. I can tell which one I'm on by how soon after my periods my wet days start. My first two days of the period are heavy, then I only have spotting for a couple of days followed by another regular period day, and then it is pretty much over. Do you think this early ovulation affects fertility at all? My 3 kids were conceived on 28 day cycles, so I'm not sure. I would love to have another baby, once my health has improved.
