there are loads and loads of threads about VBAC
also, you can labour on your terms, and can decline constant monitoring, www.aims.org.uk is good for helping you with this sort of thing , if you are being told you have to labour a certain way.
also, it is worth looking at why you 'failed' to progress last time.. e.g baby in a funny position, immobility, feeling scared and unsupported can make labour slow ,
being overdue can lead to meconium in the waters without it meaning baby is distressed
I had a VBAC after em c.s first time for failure to progress, i got to 2-3 cm, so never even got into established labour, but my VBAC was a straighforward, intervention free, birth, i did not tear either, despite baby being persistent OP and born face up.
if there is no medical reason that is likely to recur, it is worth, IMO, going for a VBAC, being prepared, reading up on it, making informed decisions about how you want your labour to go, knowing the pros and cons of the different types of pain relief etc.. and having a doula can definitely increase the chances of a succesful VBAC. also have a find a doula directory here that is free to use
