Hi
@Nadia Robertshaw . It can take a while to learn how to very technical term here bodge

your finger and persuade enough blood to appear.
Here’s a few tips .
Use the sides of the pads ,not near the nail, with a bit if juggling you can use both sides.
It’s recommended we don’t use our thumb or index finger, in case of soreness or infection as they are the ones we use most, personally I’ve always ignored that bit of advise.
To help get the blood flowing, wash hands in comfortably hot water, making sure fingers are properly dry before testing else you will get a false result .
You may have your lancing devise set too high, try turning to the 2nd lowest notch and work up gradually till you find the setting that works for you.
If your re using lancets , it might be blunt and need changing even though it’s not St Swithuns day
After bodging your finger, wait a few seconds before gently squeezing finger, I used to find a rolling action best.
I hope you find this helps.
