Should I just go to the hospital to be sure?

I've been cramping a lot the past 2 days with sharp stomach pains here and there. I'm having a good amount of discharge( clear and milky white), extreme hot flashes with 30 minute increments of having trouble breathing.  Also I have lower back pain pretty bad. Everytime I call a doctor they kinda just say "oh it doesn't really sound like an emergency but you can come in if you want" I'm on the fence because I see a lot of women have these symptoms here and there so it seems normal? Also when i poop it's diarrhea . I'm 35 weeks tomorrow. As for my baby's movements they have slowed down this passing hour but I still feel her moving (head pressing down on my pelvis)
