I get this too, mostly on the left side, but it feels like the baby kicking! So, I wasn't too worried, yet.
if it makes you feel any better I think we have the same thing. I get strong sharp pains on my left side once in a while. Mainly when I lay down on that side or when the baby puts pressure there. Gonna ask my midwife for both of us on the 3rd. Best of luck. HUGS*~Kelly
