Losing plug 34w/2d

As

I'm losing parts of my plug. Yesterday I lost a big string of it clear, loose and snotty-like. Probably 2 inches in length. Today I sat on the sofa and put together my changing table, stood up and saw a wet spot on the sofa seat cushion about the size of softball. I went to the bathroom shortly after which I noticed upon wiping another couple small globs of thicker white strings. I've been feeling lightly cramp-y all day sort of like what you get wth diarrhea. Also the past couple days I have been feeling a little more pressure there than typical, causing me to pee almost double the amount of times during the day. What do you ladies think is happening?
