Message from my GYN????

I had my annual exam about a week ago. Today, I received a voice mail from the "advice nurse" (whatever that is) saying that I needed to call them. I was told I would get a postcard saying that either everything was normal, or it wasn't, but it may take up to six weeks. Here it is a week later, and I'm getting messages. Should I be worried that something is wrong? I know I should wait and just call them tomorrow, but I don't think I'm going to be able to sleep for worrying about this. Has this ever happened to anyone else? And is it usually bad news?
