That's what I heard too. I also heard RLP was only off to either the right or the left. Mine was dead center most of the time and lasted so it was nothing like what you read about if you do a google search for "round ligament pain." However my u/s was normal, baby's heartbeat was normal, my cervix looks like it's supposed to, and I've heard from other bumpies who have had similar experiences so I can't imagine what else it could have been! Remember it's OK to call your doctor anytime you have a concern. For me, going in and hearing the heartbeat and hearing that my cervix was A-OK helped me a little.
