I accidentally took my nuva ring out a week early what should i do? should i wait til when i was suppose to put the new nuva ring in?

No worries: Just either put the used one back in or place a new one. If you place a new one, you will remove it in 3 weeks instead of 1 week.

Check NuvaRing URL: "During Week 3, do not reinsert the NuvaRing that has been out of your vagina . . . Use another birth control method, such as male condoms with spermicide, until the new NuvaRing has been used for 7 days in a row . . ."
