Somebody please help... TMI!!!!

So I've been cramping in the top part of my belly really badly. Nothing seems to work ( ginger ale or Gatorade ). I have really runny #2. I'm 25 weeks pregnant. And the cramping isn't really like stomach bugish. It's actually just comes and goes every 15-20 minutes. I'm not throwing up or anything. This has been going on since Monday afternoon and it's now Wednesday HELP!!!! 😩😩
