What causes pelvic pain in pregnancy?
It's very common for mothers-to-be to feel twinges and aches in their lower abdominal area, especially during the first and second trimesters. As the uterus expands, the round ligaments (elastic bands of tissue) that support it are stretched and pulled. You may feel this as a sharp pain or a dull crampiness on one or both sides of your abdomen. If you experience severe or persistent pelvic pain, especially if it's accompanied by a fever, call your healthcare provider immediately.
