I hope it is not UC related but it could be. I have had some soreness like that before and since you are having some cramping and loose stools I would try to get it under control asap. I know from first hand experience that many women flare a few weeks after giving birth. It is stressful enough to have a new baby at home and to be getting less sleep...you sure don't want a flare that gets out of control. Congratulations on your new baby!!!! I am pregnant with number two!
