Don't know anything about your choice of hospitals, sorry, but if you want to get into a KYM program then you need to book now!! After you have been accepted then look into HB. You an always cancel your KYM place if you decide to HB but you can't always get into a midwife led program if you wait to long. And by to long I mean 6+ weeks.
Even though you haven't been and confirmed with your GP I'd still call. Spots fill up really fast.
