Has any other lady here experienced sudden stomach pain localized to one side of the stomach and back. It was a sudden pain and I can’t find a comfortable position for it to go away. Can’t stand up all the way either. If I do it shoots down from my ribs,almost around to my belly button, and around half way through my back to by women. Could it be a muscle? Round ligament pain? Over stretched or pulled muscle? Should I call my midwife or wait a little longer? I’m 25 +2 if that helps.
