I found this on the NuvaRing website http://www.nuvaring.com/Consumer/patientSupport/nuvaRingHelp/index.asp?ComponentID=76346&SourcePageID=74639#1 I hope it helps. If NuvaRing
Yes, you can do so with no additional risk of pregnancy. You may have irregular spotting or vaginal bleeding in the next cycle, though.
No, it will not.
Yes, inserting NuvaRing before your period can delay bleeding.
Yes, you should remove or replace the NuvaRing on schedule regardless of any bleeding.
If you inserted NuvaRing during your period, you're likely to bleed again in two to four weeks.
The signs of pregnancy on NuvaRing are positive pregnancy test and missed periods. Take a pregnancy test if you think you might be pregnant.
After 29 days wearing the Nuvaring, you remove it (for 7 days). Then you get your period and you use the softcups. You're period is already over, when you have to insert a new Nuvaring. So you''ll never have to wear both at the same time. a user of both ;-)
Yes, inserting the first NuvaRing will often shorten a woman's period.
Yes
Yes, but if you're doing so just to prove you're not pregnant, reconsider. Just take a pregnancy test instead, and continue using the NuvaRing on schedule. If you're trying to change the date of your period, just use the NuvaRing without taking the week-long break, rather than stopping the NuvaRing early and putting yourself at risk of pregnancy. Contact your health care provider for advice specific to your situation. If you want to stop NuvaRing, it's fine to remove it early. There's no other reason that I can think of in which removing NuvaRing early makes sense.
If you start using NuvaRing on day one of your period, you will be instantly protected because you are not ovulating. If you wait until days 2 - 5, you could not be protected if you have already started to ovulate.
Skipping your period with NuvaRing does not increase the risk of pregnancy. Using hormonal birth control with a shorter or absent break may actually lower the risk of pregnancy.
You wait the 7 days and put another nuvaring in. You'll only have a period if the hormone level is low enough, some people lose periods altogether on the nuvaring.
If you have not had sex you know you are not pregnant, it is possible the hormones in NuvaRing are enough to prevent the withdrawal bleeding you had while on BCP. One possible side effect of the NuvaRing is for bleeding to stop completely. You should replace the device on the day it is due, if you have withdrawal bleeding or not. (more information at link)
