You should call your doctor. A friend of mine had fibroids that sounded like that

that sounds to me like your noticing where the baby is lying :) when you get further along it will get more noticeable :)

My cousin had something similar and turned out she was constipated. Try not to worry.

Sounds like you are seeing the shape of the baby.
