Question: how soon after taking out nuvaring does period start?
Answer: Wear a ring for 3 weeks (21 days), 4 weeks (28 days), or 5 weeks (35 days). Then take it out for the next week (7 days) — that's when you'll get your period. After 7 ring-free days, put in a new ring. Take out your old ring and put a new one in on the same day of the week every time.
