CM question

Haleigh
So today (cd13) I randomly get egg white cm, I say random because my periods are 35 days long and I usually don't ovulate until like cd18-22. It kind of explains why I've been really wanting to have sex the past few days. Lol
My question is: how long do you have from the time you get the egg white cm to when you're supposed to ovulate? 
We haven't had sex in like 4 days so if we did tonight would we have a decent chance of getting pregnant?
