I think I'm married, but I'm not sure.?

My Fiancee and I went to the courthouse and got our marriage license. The judge signed and stamped it. We didn't say any vows and we didn't have any witnesses, so are we married? All they had us do was raise our right hands and swear that we didn't lie about any information given. We never talked to the judge and it only took 15 minutes. Could someone get back to me soon about this...I'd like to know if we're married or not. Thank you.
