I was unsure when to trust my CGM and when to check again

I've been using CGM readings to understand my glucose patterns, but I still get confused about when the CGM number is enough and when a finger-prick check is needed.

I know CGMs provide continuous information, but there are situations where people double-check with a glucometer. I'm curious how others decide when to rely on the sensor reading and when to confirm it another way.

For people who use CGMs regularly, what situations made you do a finger-prick check? Did you learn any practical rules that helped you feel more confident using CGM data?

When I first started using CGM, I wanted to confirm almost every unusual number. Over time I became more comfortable understanding when a reading looked reliable and when I needed to double-check.

Same experience here. The confidence comes with learning how the sensor behaves for you.

I still keep a glucometer because I don't want to depend on only one source of information. It gives me peace of mind when something does not match how I feel.

The biggest thing I learned was that trends are often more useful than one isolated number. Seeing where glucose is moving helps me understand the situation better.

This is what I like about CGM too. The pattern around meals and activity tells a bigger story.

I learned not to ignore situations where the reading does not match what I expect. Having a backup meter available makes those moments less stressful.

That makes sense. The CGM is helpful, but having another option available can be reassuring.
