All cuddled up

As I'm doing this, I'm having cramps... Like period cramps, can't even
walk straight and move from side to side... I called Uls to come home
early from his internship... I was wondering if this is normal or
should I go to the ER...b/c I'm crying- that's how painful the
cramps...could it be braxton hicks(?)... My baby is moving tho
