I get them alot now around the bottom of my belly and on the right hand side, it is just your baby shoving everything out the way, the ones on my right hand side is the musles stretching, the ones on the bottom I think is my bladder (As it is always full, plus I don't go as regular if you get my drift) plus the added weight! Midwife said it is normal and good shows that something is happening! *GROW, BABY, GROW* I think We should feel it around 20 weeks give or take a few weeks when the baby as more room to move around!
