Are we screwed if Dexcom G6 comes off early?

I just switched from g5 to g6. When I had the g5, I didn’t really worry about it if a sensor got caught on something and came of after a few days because it always kind of balanced out with the sensors that stayed on past 7 days. With the g6, if a sensor comes off after two days (like it just did with my first one) am I just screwed when I end up short at the end? I want to put in a new one, but I’m worried about ending up short towards the end of three months. Ughhhh this never gets easier.
