I just found out I'm prediabetic and my doctor wants me to test my blood four times a day, I've tried like fourty times on every finger and the two alternative testing locations (wrist and palm) and I can barely get any blood. I've tried with and without the safety cap and have also tried it on every setting available. Even when I squeeze my finger it doesn't do anything it just hurts :((

So idk if this is just a crappy tester (since it was pretty cheap) or if I'm doing it wrong ;x; I did it exactly like it said in the book.

Edit: Also I'm using a needle lancet, but at the doctor they used a sort of blade lancet so idk if there's a difference ;x;
