Hi, Hope some experienced dexcom users can help. Am new to Dexcom and so far think its great but i do have a prob attaching. This morning went through usual process and pinched skin, pressed plunger all way down. Think if honest i forgot to put fingers underneath hood and pulled back to wait for 2 clicks. Instead i placed fingers on tothed based and pulled back resulting in the rubber sensor (with 2 black holes) disconnecting. I am concerned the sensor has been left under my skin as not visible? I cannot see anything sticking out but would appreciate any help or advice or if i need get removed?
