glad you went for check and little one is fine! the cramp is on off rite? pls dont be too worry! i used to have that too! even like now, the cramp and pain is like moving all over the abdomen and lower part.
i guess its the wind trapped inside the body. i remember a malay massage lady mentioned before, these trap wind if not release out from body, they could move all over and cause the pain.
i did rubbed softly on my abdomen, and when it passes out, i felt much better!
anyway, just rest more n tk care!
