How soon after inserting a new NuvaRing can you have unprotected sex without getting pregnant? It is not my first time using it.

vaginal ringGreat question! The NuvaRing is very effective in the prevention of pregnancy, but only if you use it perfectly; however, it doesn’t protect against sexually transmitted infections. It’s never a good idea to have unprotected sex. To lower your risk of pregnancy, use a condom for the first 7 days following the first time you use the vaginal ring.
