Girls today all day my belly hurts like I need to go pee and I'm walking and nothing. In between it aches like during my period. Could this be Braxton Hicks contractions? The plug hasn't come out. I have a scheduled C-section on October 12th, should I panic and call an ambulance or is this just false alarms? I don't know how labor starts, what kind of movements should I expect because my previous birth was also complicated, so I'm in a daze.
