It's nearly 8 am here and I woke up at 3 am with periid like pains. I haven't been able to time them as it's pretty much constant but I managed to sleep for an hour. Sometimes my stomach hardens and sometimes it doesn't but the period pain is constant. I had a bath to help which it did and I'm back in bed but period pains are back. I'm 40+1 is this the start of labour? Answers please
