Our 34 year old pregnant (15weeks) daughter has been experiencing severe stomach pain sinks Monday of this week. Her OBGYN said it must be food poisoning, however, her internist told her today that food poising should pass in two days. Her internist will refer her to a gastro specialist tomorrow if the pain persists. As of right now, she is having severe stomach pain. SHe has had firm stool today whereas that was not true on Monday and part of yesterday. As her parents, we are becoming concerned she is experiencing something mor severe?
