Mucus plug

My mucus plug came out 2 weeks ago. It was brownish. 4 days ago it come out white clear. Now it’s coming out in pieces. When will labor start. I’m 36 weeks and 4 days. My back and legs are killing me. I getting shocking pain throughout my legs down to my feet. I can’t even get comfortable at night to sleep.

I do have twin girls that are now 4 but I never experienced this with them plus I was induced at 36 weeks with them due to one of the twins not eating.

I really want to email or have a phone call with my doctor and tell her if I can get induced.
