Dog tags

I lost my dog tags for work, I lost them and I'm scared that my girlfriend found them because I wasn't supposed to have them on me, I already lost the bolt that we get rewarded but I didn't think I'd lose the dog tags. So now I'm scared that she found them. I really hope she didn't because that would make her mad at me and I don't want another argument, as I said one more argument and I'm out. But idk if I got all the stuff I'd need from her house
