Help

We are getting married in 19 days. We had registered for gifts at 4 different locations per request of different family members. Due to our very large families and very gracious family and friends I had two showers and we've recieved almost everything off of our registries. I was hoping that this would be a hint that money would be appreciated but instead I am getting grief from all different sides that I need to add more to our registries. I don't want to sound ungreatful at all but we don't NEED anything else. We don't know where we are going to be living and since we were both somewhat established prior to getting engaged we had things that people register for (pots, pans, applinces, etc.) I refuse to just add random things so that there can be more items on them.
What do I do? I'm tired of the nagging. I registered at a store that I didn't want to and now have $700 worth of credit. I want to just delete the damn registry. Any advice?
