Started a couple of days ago and it's really unsettling. It's around the middle of my stomach so parallel with my belly button and it honestly feels like there's something moving around in there under the surface. Doesn't seem related to eating/digestion because I'm experiencing it in the morning before I've eaten, after food etc to the same extent. I'm 47 so wondering if it's some weird peri-menopause symptom I've not heard about. Any ideas?
