has anyone else experience there tummy vibrate or shake at 30+ weeks?

thanks @mamabear9456

Haha! @green7dusty .... I've felt this already and I'm 25 weeks. I read it's your uterus spasming not anything to worry about or anything

I don't know, but I imagine he's shivering or I'm having a phone instead of a baby

what causes that? I thought I was crazy for a min, but I've felt it a couple times now

Yes
