We have had the results of all our blood-tests and B's other test back. They are all quite normal. No easy solution to our conundrum there then :-(.
I have an appointment with the gynae clinic on the last day of December for some further tests ... I suppose it goes without saying that I'm not thrilled at the prospect. In the meantime we are doing our best to make further tests unnecessary - luckily it is the time of the year for early nights and late mornings :-).
