I am noticing, once again, the Libre is getting "stuck" at 53 especially is she's just laying down sleeping. The last contour reading I got was on the low side too 65, while Libre said 54. Because it's doing that, I think maybe it's faulty somewhat. It does get higher when she gets up and around and when she eats. Therefore, I'm not relying on the 53s and 54s I'm getting with it, but I am still putting all those numbers in her SS. I also know that if it falls below 53, then I need to test her because when it acts like this, 53 is the "magic" number.
I do know that it's not off by a huge margin anymore. If it's reading in the 50s and I test her and she's 70s or higher, then it catches up with that as she gets moving around. Maybe it just gets stuck in stagnant readings.....
I detailing all of this in hopes that it helps to understand it a bit better and possibly help anyone else who might be new to using a libre and/or having similar problems.
I did get the first replacement sensor I requested delivery yesterday and I requested 3 more today that they are sending out so I didn't waste my money on the ones that didn't work.
