Hi ladies -- I have very long cycles but what's also weird is each cycle seems to be a different length. I have all this info in glow. This month glow predicted I'd ovulate the first week of November. I used those pee on a stick tests all week but it was never positive for ovulation! I think a few days ago after I ran out of tests I possibly could have finally ovulated because I notice EWCM...but I'm not sure. I included all the cycle info I have below. Do you think something Is wrong? How can I tell when approximately I'll ovulate next? Do I have pcos or something worse?? Please help!

Menstrual Periods:

July 25, 26, 27, 28, 29

September 6, 7, 8, 9

October 15, 16, 17, 18

Estimated by glow for November 25, 26, 27, 28

July to Sept 43 day cycle (1st day of period to day before next period)

Sept to Oct 39 day cycle 

Oct to Nov est. 41 day cycle
