Girls, hi I have such a question My belly is rumbling at night and there are constant urges to the toilet, and it hurts on the left side of my abdomen, specifically at night, I'm 35 weeks pregnant What could this be? I have a new gynecologist because my old one went on vacation, I asked her and she didn't say anything, like "that's how it should be?" or something? Has anyone experienced this? It's really hurting.
