I did the same thing for the first couple of tries.
Try testing on your forearm, it doesn't hurt nearly as much. I hope you have a meter that allows forearm testing, because it really helps. I have arthritis and testing on my fingers is just too painful.
I did some comparison testing when I first got diagnosed, and my forearm numbers always seem to run about 1.5 mmol/L units higher than my finger test shows, anytime that my blood sugar is falling. That means that if my blood sugar is getting low, and I do a test on my forearm, the reading I get is about 1.5 points lower than the reading I would get if I had done the test on my fingers. I got these results consistently over many trials, so I know I can rely on these numbers. It may take about 10 to 15 minutes for the blood in your forearm to have the same reading as the blood in your fingers. The hands have a fresher blood supply. That's why your supposed to test on your fingers. You can also test on the side of the hand that runs between the base of the pinky finger and the wrist, and also the base of the thumb.
One important step to forearm testing, is to rub your arm a minute before you take the test, so that there is fresh blood in the area before you use the lancet.
I use a Freestyle meter and also a One Touch meter, both of which allow forearm testing. I prefer the Freestyle, because it uses a much smaller sample.
You can see a diagram with the testing sites for the Freestyle meter marked on it in blue. Freestyle can be used in several places, not just the hands and forearms.
