Hi, I'm very new here and have started following Activity2004. She is very informative and encouraging. I have a new Dexcom and hadn't changed the sensor in 10 days because I was afraid to do it by myself. Watched the youtube videos on it and finally did it today. All went well but when it came to putting the sensor in, it seemed to take brute force. I hope it is alright. Any advice will be very welcome.
