Ladies I need some advice. I'm having extreme cramps they hurt so bad it wraps around to my back. on a scale 1-10 its a 7. Also I have been vomiting all day I can't even hold down water. I just miscarried in January so I don't want to go get check if it's nothing. what do y'all think should I go get checked?
