If you used Nuva Ring correctly during the previous three weeks, and are in your ring-free week, you have the same level of protection that you had in the prior three weeks.
If you accidentally had the ring out for three days in the middle of your three week "ring in" time, you should use a back up method for the next seven days, and consider using emergency contraception.
If NuvaRing breaks, you should replace it with a new one, but there's no special risk of pregnancy.
Yes, there is a chance that you could be pregnant if your boyfriend ejaculated inside of you without your nuva ring in.
If you had it out for more than three hours, you should use a back up Birth Control method for the next seven days.
As no birth control is 100%, and as it apparently didn't exist for one night, then yes, there is a chance you could be pregnant.
If an accidental pregnancy occurs, the Nuva Ring should not cause a miscarriage.
There's no need to stop using hormonal contraception, including Nuva Ring, for as long as you don't want to get pregnant. Nuva Ring and other hormonal birth control methods have no effect on future fertility.
The Nuva Ring birth control device can fail if it is left in too long; if the device comes out of the vagina and is not reinserted within three hours; or if you have unprotected intercourse when just starting using the Nuva Ring and it has not been in place for at least 7 days. http://en.wikipedia.org/wiki/Nuva_ring
Pregnancy is possible, but Nuva Ring is a highly effective method. Pregnancy is unlikely in the situation you describe.
Nuva Ring reduces the risk of pregnancy while you use it. After stopping Nuva Ring, women do not have a decrease in fertility. 85% of couples using no pregnancy prevention will get pregnant within a year. This number is the same for couples who have used Nuva Ring, and for couples who never used hormonal birth control.
yes it will.
According to the Nuvaring website, the levels of protection from pregnancy do not drop if the ring is outside your vagina for less than three hours. If you remove the ring for more than three hours, you may become pregnant.
If 1,000 couples use Nuva Ring perfectly for a year, three will get pregnant. Since there are no perfect couples, pregnancy rates with typical use are higher than that, but there are no good data to date on typical failure rates with Nuva Ring. It's probably lower than typical failure rates with the pill, for which 8 pregnancies can occur among 100 couples using the pill for a year (higher for teens). After stopping Nuva Ring, women get pregnant at the same rate as women who never used Nuva Ring. It does not impact future fertility.
If the ring was out for less than three hours, you still have the normal level of protection. If more than three hours, you might consider using emergency contraception, and need to use a back up method for the next seven days. If you think you might be pregnant, check with a pregnancy test. Short bleeding is not unusual with Nuva Ring.
Not effective at all, I was a week late on the neuva ring and got pregnant!
If you used Nuva Ring correctly in the previous three weeks, there is no increased risk of pregnancy during the ring-free week.
