She was lovely! Referred me for more blood tests & dh for another sa and we've got an appointment to see Mrs Wallace in a couple of weeks. Meet Mrs Wallace too as she had to come in to get some paperwork - she introduced herself and kept apologising for interrupting. So all in all it was a much better than I'd imagined! Reading this thread had really put my mind at rest though. Can't believe how lucky I was to find it the morning before my appointment.
At the end she asked why we waited so long before seeking help (ttc since end of 2009, dh & I both 34), but the dr who eventually referred us after a lot of persistence had warned me they might say we hadn't been trying for long enough!
Thanks again for this thread, we'll have to start a Nurse Burke fan club!
