Round ligament pain?: Pain with activity in early pregnancy is often caused by the round ligament on the sides of the uterus stretching. Your description sounds consistent with that, but you should check with your doctor. Other things that may cause pain on the sides of the uterus include infections, cysts, or even an ectopic pregnancy so you need to check with your doctor to be sure.
