If you been on nuva ring for 6 days and you have unprotective sex what are your chances of getting pregnant?

If it's your first cycle, and if you started the ring on the very first day of menstrual bleeding, there's no increased risk. If it's you're first Nuva Ring and you started at some other time in your cycle, you should have used a back up method, like condoms or abstinence from vaginal sex, for the first seven days of that first cycle. Consider using emergency contraception, and continue using the ring as scheduled. You can take a pregnancy test no sooner than 10 days after unprotected sex.

If it's your second or later cycle, and you used Nuva Ring correctly in the prior month, there's no increased risk.
