hi, if you reach your due date (it's quite soon isn't it?) then I'm sure your m/w will give you a sweep, but they only work if your cervix is ripe and ready! it doesn't really induce as such, rather just encourage things along the way.
I can empathise with how you feel as I was like this with my second baby, desperate. but the best advice anyone gave me was to try really hard to relax and wait for it to happen. sounds really daft though I'm sure but there is some logic in being in a relaxed state in order for your body to begin labour.
have you tried litening to relaxation tapes? I find them so helpful in the later stages of pregnancy, they don't have to be pregnancy related, great if they are. it also takes some practice to let your self go and just listen, but well worth a go I reckon...
