I haven't had anything that resembles that glue you mentioned. But I have had the odd jelly-like CM which i almost had to 'pass'. I could feel it coming out when went to the loo, and it was a solid blob of wobbly mucus. V wierd. I never got it checked out tho.
I get this jelly type stuff and it's what I call my egg white CM. It's a glob of jelly goop!
