35w&3days pregnant!

I'm having really bad pressure in my vagina area and around the opening of my vagina. It feels like something is coming out of my vagina. I went to the bathroom with a diarrhea cramp starting and then it got really bad. I had cramps in the front and my back and the pressure got worse and now it's pressure and feels like something is coming out. When I went to sit down on my couch I had the same thing as I did when I was on the toilet. It hurt so bad. I'm a ftm so I don't know what to expect. Does this sound like labor coming soon? My water hasn't broke and my mucus plug hasn't fell out. But it feels like something is coming out of my vagina.
Please help!
