OPK and PCOS

Kazia

This is my first time posting. Diagnosed with PCOS 5 years ago. TTC for 3 years. Have been using OPK for over a year. This month has been odd with the OPK. 14 days of High Fertility with no peak. Has anyone else experienced this madness? My cycle has never been regular but 14 high days when they are to last 5-10 seems a bit extreme. Can I really just be fertile for half a month?
