I also had bad cramping early in both of my pregnancies. I also had abdominal pain from gas. It was very sharp and painful. You can take gas-x for it or Maalox. Or you can go on your hands and knees, then put your forearms on the ground and leave your rear in the air and it will help relieve pressure.
Can you be more specific about the pain? During my first trimester I had really bad cramping. But it's because the ligaments are stretching and your uterus is expanding. But if you ever have any questions or are concerned about it, I'd call your doctor. Good luck!
I would say go to the doctor! You shouldn't be alot of pain this early in your pregnancy. Good luck and keep us updated! Praying for you and your sweet baby!
