Ovulation help..

Tara

I’m so confused, I was due to ovulate tomorrow and today to be my peak.. I know going by the app it’s only approximate.. although my opk’s have been negative and pushed back my ovulation till Saturday. I’ve been having a ‘creamy’ although at times veryyy raw egg white CM.

Anyone help me out at all, can you ovulate without a positive opk?! Just going by your CM? Photo of CM atm
