Hurrah, that’s excellent news @lizz
I always wear my pump and sensor on the same side like you. If I wear it in my back, I clip my pump to the side of my waistband rather than the front, that way the signal doesn’t get blocked by my body in the night.
Have you tried your bum? I’ve not, because I quite like to use it for infusion sets but I know others have. I know some people use their arms too, although the thought of it makes me feel a bit queasy.
