This is my 2nd pregnancy and Omg, I was sitting down and felt the biggest roll ever. The baby rolled across the highest part of my leg and my right arm. I literally jumped and screamed. Haha! It was so wierd feeling because I didnt feel him inside just outside...it felt like a snake slithered between my belly and arm! My husband just looked at me laughing when I jumped out of my chair. Anyone else experiencing huge rolls at 31 weeks?
