All, some feedback on the amazing nhs service I've recieved so far (we opted for queen charlotte's) since my initial, nervous, post:
First, I was referred to my initial midwife appointment in a little children's centre/clinic in hammersmith, surrounded by flowers, where I was greeted by a relaxed, smiling receptionist. Lovely midwife called Karen took 1.5 hours (yes, 1.5 hours) to go through my medical history and assess my needs. So friendly and caring.
Next I went to Queen Charlottes for a blood test only to realise there were about 20 people in the queue before me. As I'd arrived at 1, and had to leave at 3 to pick up my children from school, I timidly asked a nurse if my having allowed 2 hours to queue for the test was realistic. 'Ah, bless' she replied. 'If they haven't done it in an hour come back to me and I'll do it myself'. I've subsequently discovered she's the head nurse and an incredibly devoted and caring about her patients. Another nurse, who took my blood within the hour (time for me to have lunch at Costa coffee which is conveniently on the same floor), was delightful and we chatted about schools, her boys etc.
Third, I returned to QCH yesterday for my first scan: no sooner had I arrived than I was seen. They were all friendly and answered all our tedious questions despite my having forgotten to bring any of my paperwork.
I have yet to deal with a single nhs staff member who didn't smile or immediately address my concerns about my pregnancy. And what a smart, clean, impressive hospital Queen Charlotte's is!
Thanks mumsnetters for all your feedback & advice and, more important, a HUGE well-done to the NHS.
