Is there such a thing as registry Etiquette?

I’m almost done with my registry but I feel like I have too much ... about 100 items . I obviously will be happy if I recieve one or two gifts regardless I’m not expecting anything . I’m just wondering if there are rules to this shit or something lol. Like adding too many items , or too expensive ?
