I never know if it’s the correct place. I think it’s too low down tbh. But the first time I put on a Dexcom it was in a similar position and I had no compression lows! Unlike the last sensor!
The general rule of thumb is to not place it over muscles and place it in more fatty areas. “Approved” locations for the Dexcom G6 are the backs of the upper arms or the abdomen although many people place them in other areas.
