Birth control and cm

Okay so this may be long but I’m trying to understand my body. I’m on birth control and I check my cm everyday and either there is nothing there, or it’s a white creamy discharge. I know that my pill is supposed to stop ovulation so that makes sense. I also know that before I became sexually active or used birth control I would notice the egg white cm that is linked to ovulation, but at the time I had no idea what that meant. So does that mean that as long as I don’t have that egg white cm anymore, then I’m probably not ovulating and my birth control is working? Can you still have a lot (maybe not a lot but enough to be in your underwear) of discharge and still not be ovulating as long as it is the creamy kind? What if you don’t have any discharge at all that day, could you still be ovulating?
