Im soo scared. please help me iim 38 weeks pregnant?

First thing you have to do is calm down. The baby is probably fine just nervous because of all the drama. As long as you are not bleeding you should be fine. If the cramping gets worse then you should go to ER, but more than likely if you just calm down it will be ok. The baby is well protected in there and falling on your is not enough to harm him. Just relax and it will be ok. As for your dad and bro, I don't know how to help you with that, but you have to worry about yourself and the baby. If they fight again call the police to get in the middle and you stay out of it. Good luck!
