CuriousCucumber asked
Does the NuvaRing start working to protect me from pregnancy immediately following reinsertion after my period or does it take a week to readjust every month?
At a glance
- If you begin NuvaRing on the first day of your cycle, it will work immediately to protect you from pregnancy. However, if you are switching from a progestin-only birth control method (e.g. a 'minipill), it is recommended by the manufacturer to use back-up birth control for 7 days.
Answer
The NuvaRing, a combined hormone contraceptive ring, will provide protection from pregnancy as long as you begin using it on the first day of your cycle.
