New Dexcom user

Just got my new Dexcom Dec 28th and so far very impressed!! Hoping to get better numbers once I get off of the prednisone for a sudden hearing loss!!! I have increase basals to cover for insulin resistance without a care,something I would have went crazy over with fingersticks every hour.

Definitely keep us up to date on the new Dexcom.

Question on this - after insertion, you get the ??? - Does that mean it's no good? I mean it hasn't said that it failed and no sensor error #. Anyone know?
