Hi missionary6797, welcome to the forum. Maybe someone using a CGM, hopefully a Freestyle, will jump in and offer some tips and advice on sensor placement. Nothing beats personal experience. Unfortunately, I don't have it, but I know a couple of members who do with the Libre.
Feel free to share as much info as you feel comfortable sharing about yourself and your diabetes. What type. 1 or 2, how long ago were you diagnosed, how's it gone so far, what you do to control your blood sugar - diet meds, exercise. Don't be afraid to ask questions, the only bad ones are those not asked.
