How soon would you go to a doctor and get tested

So i missed my period for about a week now. Still no period, not many symptoms either, but the tests are still coming negative. Are the test really as accurate as they claim after missed period? Should i not get my hopes up being happy that still didn't get here? It's a Rollercoaster having my husband asking me status every day, getting happy i don't see anything yet there, and then sad to see negative over and over again. How much longer should i wait to test again or to go test it at the doctor? Thanks for your opinions
