sloane - I used to have a cup of tea at morning tea after I tested (with milk and sugar) and also at my afternoon snack again with milk and sugar and it didn't raise my levels. I was lucky enough to meet a type 1 diabetic at work and she really helped me steer towards the foods to suit and told me that tea generally doesn't do much towards your levels and she was told she could drink tea normally however having read what myson wrote I guess that actually doesn't apply to all. It is very unusual how each person reacts differently to different foods and really makes the whole thing that whole much more difficult.

CAH - It sounds like you are certainly eating enough food so that shouldn't be the problem. Have you tried ditching the test strip pack you have and putting in a new one and seeing if the levels stabilise? If they remain the same then the pack is ok and you can use again but if they are different then might find you got a dud pack of test strips. I know my glucose meter could let me run a test on it to check it was working so maybe have a look in your book to see if yours has that.
I also had trouble getting blood out and found the best way was to run my hands under really warm water and then massage the finger I was going to use for about 20-30 seconds before doing the test. In the end I used 3 fingers in the same spots to get my blood and those 3 fingers served me for almost 8 weeks without pain. Make sure your hands are dry when you test otherwise I did find the blood would run down the lines really quickly. If it hurts on your pinky finger but you find it has a good blood supply simply turn your pressure gauge down for that finger. I only ever used the 2 or 3 setting for any fingers and always turned it to 2 for the pinky finger.
Like you, I also questioned my diagnosis as I only had 3 slightly high readings my entire PG and at the end I was eating cake and all sorts without raising my levels. I was even eating foods trying to spike my levels at the end just to see if I could and I didn't.
About retesting - yes Megan is right is does just depend on your situation with endo/clinic vs OB/midwife or whatever options you have. I had to email in my levels each fortnight to my endo and if they saw something they didn't like then they simply asked me to go in (never had to thankfully) but my meter also had the option to view my average across all tests so I could also give them that during my appointments straight from the meter so my endo knew my average (obviously if average was completely different to what your levels had been they'd know you'd fudged some levels).. So I didn't have any further blood tests for the GD but you will have to retake the 2hr GTT test once baby has arrived (about 8-12 weeks post birth) plus they may get you to do some random tests during your labour and also during your hospital stay.

Happy testing ladies - remember the end is in sight!
