I've been have really sharp pain in my right hip constantly, it won't go away, but my belly tightens every 4-5 minutes. My back is about to explode and I've thrown up atleast 5 times in the last hour and a half. I can't tell if it's round ligament pain and just a stomach bug but I can tell you it feels like I'm going to die. I can't keep any drinks down, and I've had diarrhea all morning. 😭 should I call the doctor ??
