I'd just call them back tomorrow and ask for an appointment again? Do
you have a ob/gyn you could go to who might be able to reassure you thru
either a scan or an "internal" measuring by feel kind of thing? Maybe an
independent midwife you could call? I'm not sure where you're at and how
your system usually works, in germany all scans are done at the
gynecologist in his practice, except if there's something that requires
a specialist to have a look, then you're usually referred there. But
honestly, that practice/hospital you talked about doesn't sound so hot,
I mean what are they going to do if you come in in labour and they're
busy, are they going to have you wait a week then ;-) (please laugh, I
know they can't really do that, but you know as Sarah said, it takes
just a few minutes to fill out the form and if they can't be bothered to
take that time...)
Really, I'd give them another call, maybe ask to speak to whoever's in
charge, and see how that goes.
