Polysporin on new tattoo? Help?

Has anyone ever used polysporin on a new tattoo? Everyone told me to just get polysporin because it basically did the same stuff as tattoo cream, so I did and have been using it since I got my tattoo (two days ago). Is this okay?
I'm not sure what A&D is.... I'm just wondering if I have to throw out the polysporin now or if I can continue to use it?
