registry

I'm 31 weeks. My husband and I decided not to do a baby shower because my entire family lives in a different state and so do a lot of his family. I still had everyone asking if I was doing a registry and saying they wanted to get us something. A few weeks ago I finally did a registry and created a Facebook group and added all the family so they could see it. So far, I've had one person buy something off the registry.. baby boy is due in 8 weeks. Should I just go buy everything myself to be safe? I don't understand why everyone was asking me to register yet hasn't bought anything..
