I'm 41 weeks today and had a sweep yesterday and have been in so much pain since! I did have pains on Friday and thought it was all starting, even got the pool ready for HB but they went off. 
Had more pains Sunday night but again they eased off but since the sweep yesterday I have been in agony constantly. MW said I'm 2cm dilated and 60% effaced. The only positions that help are leaning over my ball or lying down but as soon as I move it hurts again.
I've got MW coming again to do another one tomorrow and while I am getting desperate to get this baby out I am dreading it. I hurt every time I move and I don't know how much longer I can cope with this for.
Did your sweep work and how long after did you go into labour? Is this much pain normal? I've been losing bits of the mucus plug since Friday so I'm hopeful it will be soon!
