I found a bright red spider with a dark abdomen which was sort of pointed in my house?

Question

I live in NJ and I have never in my life seen a spider like this. It spanned about the size of a nickel, and had bright red legs and head, but the abdomen was a dark color and was sort of pointed. I went looking online and could not find a spider to match the description. I found it in my bedroom and now I can't sleep because I am scared there are more in there. It looked wicked.
