Fertile cm but no lh surge

Kimberley

Been doing the deed every other day as you can see and Tonight I noticed I had what I think is fertile cm it's quite watery and stretches a little but I have a negative opk. I've been trying to find some answers online but not finding anything. I got a pain in my right side and that cm. could it mean I am ovulating and my opk just cannot pick up my surge?? I'm confused what should I go by my cm or a stick??
