Lost Apple Watch updated its location

So basically, I lost my Apple Watch 5 months ago either at school or at home but 2 days ago Find My updated its location to my house (Note that it’s last location was apparently school but I know I took it home) and then the next day it did the same and it did it again today. A part of me wants to believe it’s telling the truth but I think Find My could be glitched. Anyone have any ideas??
