Hi Emilou,
I find myself in the same position as you, except I'm pg with no. 2.
DS was born in a totally different hospital 50 miles away in another city, only because I had an infection that my local, brand-spanking-new hospital couldn't cope with (!)
Now, nearly 7 years later, I find myself quite literally messing myself, as I don't want to birth there this time round either. Mainly cos the whole, sparkly, expensive, flashy place is riddled with disease, I've heard so many stories of negligence, and also experienced one with my DH (they let him go home over xmas with a near-on ruptured appendix ). Add to that a death on the maternity ward (who was one of their own staff!) during labour, and that's it, I don't want to know.
Thankfully, I've talked with a couple of mums at DS's school, and I can either go for a home birth, or even, there's a midwife clinic a few miles outside of town, that will handle most types of birth, except those needing assistance (c section, or forceps I think)
So, those are my 2 first choices. After that, I'd even go so far as to pay to go in the private hospital which is only a couple of miles from the NHS one. At least I'd know I get treated like a human being, and it's a lot cleaner, even if it's a bit dated.
Other than that, I agree with flybynight - definitely talk with your m/w, and they can't make you xx
