Thanks for the advice ladies, I'll be reading that over and over again I think!

Made it to 34 weeks now, so can deliver at my hospital of choice. Up to 36 weeks they will try to stop the contractions, but after that they say they will just let me go and see what happens! So it might end up being a VBAC! Crikey, I hadn't prepared for the possibility of labour and vaginal delivery, better start reading up (is it too late to do perineal massage?).
