29 weeks and feeling off maybe tmi

Haven't felt all that great today. Been under a lot of stress lately. I've Been having a lot of vaginal pain and pressure. It still feels like dd is high up but at the same time I feel her movement really low as well. I've been cramping and having some Serious back aches that feels kinda like when I had back labor with my first. I've also been having diarrhea today. The pain from my back goes down and I have to basically push myself up to where my butt isn't on the seat and the pain isn't as bad. I do believe I am having Braxton hicks contractions. I went to the hospital a week ago for the same thing and the monitor picked up nothing and I know I for sure had a few very intense painful contractions. I have a dr appointment on the 26th but I'm getting kinda worried. And I've also been periodically having clear watery discharge at random moments with white specks. It's not constant but when it happens it soaks my underwear and pants. It's just odd and painful and last time I went to the hospital they treated me like an idiot. But something just keeps telling me something is off. Advice ?
