33 weeks and 6 days LOTS OF PRESSURE ON MY VAGINA

Hello ladies, I need help, it hurts to walk, stand, take off clothes, shower anything that has to do with movement it hurt. It feel as if I could push any second like its a big poop ready to come! TMI lol what could this mean. I have never had this before with my first pregnancy. It's getting to the point I can't do for myself. When I close my legs it hurt, when I change positions it hurts. My doctor said its normal and they are getting me a pregnancy belt. But I don't think this normal. I can't barely walk or stand without having a hunchback. Does this mean baby is on the way? Baby is big? I need help please.
