So there's times were I get this pain on my left side and it hurts to where it gives me chills, my co-worker said it's Braxton hicks but I'm convinced it's just that baby girl is sitting to one side more because when someone rubs my tummy (left side) she moves and the pain goes away. Is this what it could be? That she's just sitting to one side too much?
