I'm CD25, I have pcos so my cycles are unpredictable and sometimes long. I thought I had ovulated a few days ago, due to what I thought was ewcm and cramps, then yesterday I had a bit of what was definately ewcm and quite a bit. Then when I got home it was barely there. Did an OPK yesterday which was negative (though had very weak pee). I have just done one again, and this is what I got...I'm 99.99% sure it's positive.
