Nuvaring should be inserted on the first day of your period. If inserted during day 2-5 of your menstrual cycle or any other time, an alternative method of birth control should be used for the first 10 days. It is possible that you are pregnant. Take a home pregnancy test. Home pregnancy tests can be positive as early as the first day of a missed period.
