round ligament pain

Ginna
Has any of you ladies experiences this type of lower groin pain? How long did it last? Is it harmful to the baby? Am suffering with what I believe to be round ligament pains for three days now! One I stand up I feel pains in the lower left part of my tummy or groin area. Lifting my left leg to walk or put on my undies is a sore bitch!!! Am a first timer so don't know if this is part of the process or should I be running to the doc!
