I am 4 months and just experienced such a scary painful moment! I was walking to the train station to take my train to go home and i started to feel a jabbing pain / cramp feeling in my lower right side of my stomach. It would last like 10-15 seconds and go away, then the pain would start again until it felt really really painful and could not continue walking. Has anyone experienced this before? I read about the round ligament pain but this felt more jarring, jabbing, like waves. I am currently sitting with no pain but i guess ill wait until i get off train to see if it persists.
