Discharge TMI

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Hi guys, this is pretty gross but this discharge came out in the shower this morning and I had it on toilet paper three times yesterday. I'm 37 weeks do you think it is my cervical mucus plug coming out broken up?
