Third cycle tracking... help

Charr

Hello Ladies

last month my chart showed i ovulated on cd9... bizzare for me as i have pcos ( last months chart attached also ) - following on from this chart at the end of the cycle i never had a 'real period, it was 3 days of the smallest amount of brown stuff tmi sorry!!

so this leads me on to this months current chart ( ignore the positive opk i dont use them due to pcos i only temp i was just trying to get a cover line !! )

so can anyone help with these charts, ovulation and why the 3 days of brown stuff instead of a period?

thankyou so much xx
