Ovulation testing

Jane • Happily married teacher who loves her kitties!

Hi all. New to TTC and purchased an OPK as suggested by my GYN. I stopped my BC this month right after my last period. I have PCOS but my doc didn’t seem concerned since I had been on BC he seemed to think I would still ovulate. He told me to start testing day 11 and keep testing til it was positive. Then have sex for three days.

Anyway it’s day 17 of my cycle and still negative. I am using clear blue digital and peeing in the morning when I wake up for work around 6 am. Not sure if that is resulting in negative results or not...

Did I miss my LH surge by testing so early in the day? Should I keep testing? When is the latest day I can still ovulate?

Help please!!!
