Vibrating sensation from lower uterus area - anyone know what this is?

[emmi26]

mine did it at a mw appointment but it was at the top of my uterus. mw felt it and said imagine when you put a newborn down on a changing mat they stretch and their little legs shake. thats because they're nervous system isn't quite complete well thats what they do inside too except it feel more extreme when they are small x
