9 weeks lower abdominal cramps

Lorriane
Hey ladies so since Monday I have been having lower abdominal cramps first they were just on the left side as a sharp twinge but now they seem to be moving across the whole lower abdomen below the belly button,I don't have pressure or any bleeding like that I go see my OB tmrw I'm kind of concerned and want to know has anybody else experienced this? And Did you guys carry a full term healthy baby if so?
