39 weeks and no baby - making me :(

Hey guys,
Is or has anyone else got really frustrated when they reached 39 weeks and still no sign of labour?
Well, I say no sign but my back has been killing me. Yesterday I had signs of contractions n stiffening tummy with it for hours. Went to hospital n got sent home. 
Just feel really frustrated n so ready to get the baby out. It's my first and I heard they can take longer.
If anyone had any similar experience or advice please share ur story... X
