labour or Braxton hicks

Carina
Hi I started with back ache at 23.30 and since then it's not really gone and had period type pains in my stomach still doing it, also been to the toilet had a poo lol, I'm. 35 weeks +3 I got induced in my last pregnancy so I don't know if this is the start of labour or Braxton hicks? Husband is asleep and my 6 years olds asleep don't want to wake them for nothing?
