NuvaRing gradually releases small amounts of hormones which are meant to prevent pregnancy. The ring does NOT protect against HIV or STDs. Any information you need on the ring can be found on NuvaRing's main website. Hope this helps.
It is not necessary to use a backup method of birth control or extra protection after the first 7 days of using NuvaRing. However, always keep in mind that NuvaRing only protects against unwanted pregnancy and does not protect against STDs. Condoms are suggested for protection against STDs.
NuvaRing will not cure or treat a ruptured cyst. Use of NuvaRing may prevent new ovarian cysts from occurring.
Spotting could represent a side effect of NuvaRing or an STD. If your'e at risk for STDs, get tested. Signs of pregnancy are missing period and positive pregnancy test.

It can never hurt to be safe. If you have access to the plan B and cannot get in touch with your doctor, then take it to be safe. Having unprotected sex is not advised, even when you are using the NuvaRing, as it does not protect against STDs.

It won't work as emergency contraception, but if you're putting it in no later than seven days after your last three-week-or-longer ring cycle, you're protected. If this is your first NuvaRing, get the morning after pill and start NuvaRing. Then use a back up method until you've used the ring correctly for seven days (14 if you used ullipristal for emergency contraception).
You insert NuvaRing in the vagina.
