mucus plug rant

Destiny
So I've been loosing my mucus plug since 32 weeks, I turn 35 tomorrow.  
It slowed down for a few days to almost none and now after getting my cervix checked and found out I'm 4CM and 90% effaced I've been loosing more than ever! 
I go back to get another steroid shot tonight since he may come early. 
But do you think since it picked up a lot that means I'm dialating more? Or maybe it's just chance? I'm gonna mention it and see if they need to check it or not.
