My upper eyelid has been swollen for five days now. I think its a stye but I can't see a small pimple or anything. I've cleaned it, but its still here?

Possible concern. Eye lid swelling can come from coming into contact with something that is an irritant or from a stye as you suggested but it can be more concerning than this. I would have expected that after five days something "more" would be present and more obvious - like a discoloration, etc. I would actually have your medical provider evaluate it. You could attempt to apply some cold compresses until seen.
