Yep as disgusting as it is I also went onto google images to make make sure. Its very very thick and mucas like it can come out in one huge glob or tiny bits youd pass of as normal discharge. It can range from different colours as well if your worried call your doc
It's either brownish or greenish mucus. It can cone out in globa or in little pieces. I looked up google images to make sure the discharge I had was actually my plug. It was really helpful.
