Ohh cricket...are you sure your not a psyhcic ??? I too am pg with #4....i too have had relatively easy pg's and labours.....my last two were so quick, no tears, no drugs, whammo theres baby....but with DD#3 the contractions were bloody awful....i honestly wanted to die....if someone handed me a gun i reckon i would have happily shot myself....the pain was the worst....but here i am again....
I did find after pains with DD#3 very painful. I felt like i was going into labour again !!! Panadol did help, but pain was defn worse than with Dd#2......

Im a bit like you....im not worried abotu the labour...just getting to the hossi on time and the afterpains....
Good luck...!!!!
