Should I be worried with these LibreLink Readings? Type 2

Hi,
I purchased a sensor and I have been using it for a few days.

I don't know how accurate these CGMs are.
When I use a finger prick device it can be +2 higher.

Should I be worried and speak to my GP?

The finger tip device is the most accurate. That’s a nice flat line overnight and looks as if it’s likely to be between five and six (based on your comment above) which is fine.
 
Do you have any kind of diabetes? and are you on any medication?

The figures of themselves are ok in terms of a low bg - pretty much where I am right now according to fingerprick.

CGMs tend to read a bit lower than fingerpricks, and fingerpricks are also a bit more accurate, but not precise by any means.

As others have said finger pricking is more accurate , more painful and cheaper. The upside of the cgm is that it’s constantly there and you can see pretty much instantly what food and activities and sleep do to your glucose levels.
