Baby shower registry?

Is it terrible to feel frustrated that there aren't that many things on our registry showing "purchased"? do people not go by the registry or do they just not get it marked off? Our shower is a week away and I'm really hoping I'm not going to have to take a bunch of stuff back because we requested things/brands we like and people just decide to buy what they want😖😭😥 I know it shouldn't stress me out but it kinda is.
