Hi Belxan, welcome to the thread that none of us really wants to be on! 
Echoing that you should push to see a dietician. I'd also ring your midwife (diabetes midwife preferably, if you've got a number for one) and double check what you're supposed to be doing with your diet - do they want you eating your normal diet for two weeks so they can get an idea of what your sugars are like?
How often have you been told to test your blood? Fasting is obviously what it sounds like, you do it before you eat or before bed. You would time a 1hr or 2hr post-prandial (after eating) for the time you finish your meal, not when you start eating. That really confused me too at first, but my lovely friend has type 1 and explained it to me!
The hospital should have given you control solution with your meter, or possibly a prescription for it if it's available on prescription. You should be able to ring the manufacturer and ask where you can get hold of more as you need to use it when you set the meter up, and every so often to check it's still accurate, usually when you come to the end of a batch of strips. My meter has a cassette instead of strips, so I have to use control fluid every time I change a cassette, which is every 50 or 100 tests. I got three little things of control fluid from the hospital but have been told to ring the manufacturer to ask how I can get more.
Don't worry so much about carb counting until you've confirmed with your midwife what you should be doing with your diet over the next two weeks. Those of us that do it are either doing it because we've been given a target of how many carbs to eat at each meal; are trying to find out how different amounts affect sugars, or because we're on fast-acting insulin and need to calculate doses.
Longest reply ever! If I'm teaching you to suck eggs, I apologise! I had to figure out a lot of stuff on my own as I diagnosed myself with GD before I was officially diagnosed (don't ask).

I am now on insulin, as suspected. Only 6 units of intermediate-acting, to work in the background. I'm still carrying on doing post-prandial because I think it's useful for me, even though my hospital only want four fasting results per day. I had the annoying thing where my lunch sent me high today and the exact same lunch last week was FINE.
