Continue following all directions for the NuvaRing
. If you miss a period, take a sensitive pregnancy
test using a first morning urine, and following all the directions.

If positive, let your doctor know right away.
The worst thing to do is to panic, take out the NuvaRing and have unprotected sex. This is often how birth control "failures" happen.
