Saw the duty GP at my usual clinic this morning and he was next to useless. He didn't know anything about complications with pregnancy and didn't even know if you could get tests done. That said, given I said I wanted the test, he rang the lab and double checked and ordered the test. When I went to the path lab next door, they said it was a reasonably common test, nothing out of the ordinary at all.

I'll get results Monday and have a little vent to my usual GP about his colleague. Thanks for your advice and support.
