Blank rolls

So Ive been shooting with film for about a year now, and during all that time I’ve gotten two blank rolls, both from the same camera. Does anyone know what could be the problem? All my other rolls have come out as they’re supposed to, and I’ve developed a good amount, so I’m not sure what that could be. It seems like if it was a camera thing then I’d have a lot more blank rolls, but like I said it’s only been those two out of a couple dozen or more rolls. Maybe a loading issue? But also you’d think I’d be used to loading film by now
