Birth control and CM- TMI

Sarah • Baby #1 due July 2016! 😁
I've recently gone off birth control, period is due on Sunday. 
Not once through my cycle was my cm, stretchy or of egg white colour. Always thick and creamy... 
Is it possible I didn't ovulate or could I have ovulated buy just take time for the cervical mucus to break down, after being on the pill?
