I have PCOS, last month I didn't ovulate until CD 20. This month I got a negative OPK and no CM on CD 14, on CD 15 I had what looked like it was almost a positive and egg white CM. the following day I had the same OPK results but dry. Every day since then the line is no where near positive and when I check CM it's white and small balls. Do you think my positive was CD 15/16? I'm CD 19 now
