I remember having rib pain with DD, but this time my ribs on the left side burn. It's horrible and will actually wake me up at night. But vibrating...I'm not sure
When I first started feeling movement there were a few days where it felt like my uterus was vibrating. Maybe your LO is just moving up and you're starting to feel things where you never have before?
I get this too, and thought I was going crazy, if it weren't so consistent. Not the buzzing so much, but quick vibrations. Happens a lot when I'm laying on my side. Kinda feels like LO is shivering. It was so intense one time that I actually had a dream that LO was having seizures inside me. Such an odd sensation!
