Very Painful Baby Movements 36 Weeks

Anyone else really suffering with an active baby? I am 4'10" so he doesn't have much room in there. He is getting very low (I can currently feel his hiccups in my vagina and butt) and I lost my mucus plug more than a week ago already. His movements and pushing is killing me! It hurts so bad I can't even breathe sometimes, and I feel it in my ribs, hip bones, back, pelvis, and everywhere in between! I have my 36 week appointment Wednesday and I'm going to ask my doctor to check my cervix, because I feel like this baby is going to be coming very soon!
