Girls, who have babies in their bellies calm? Many describe strong movements, hitting ribs, sleep is disturbed or when watching on video, and there's a storm in the belly. I don't have that. It moves steadily, it has its own rhythm, usually in the morning and evening and during the day normally, but so easily and smoothly, more like kicks or a couple of pinches and that's all. Analyses, ultrasound all normal. Still worried.
