I ve had a sensation in my lower left abdomen that feels like a fetus kicking for a couple of weeks now. It can be felt by others and even seen moving, as well. I am not pregnant nor can I be--no uterus. It isn t painful, just annoying. It occurs all throughout the day. I don t have symptoms of gas (i.e.: pain, bloating, passing gas, etc.). What can this be? Should I be worried?
