How long after i insert my nuvaring should my period stop coming?

Won't stop: If you use it the normal way , it will still come, but you can insert one right after you remove one instead if waiting 7 days and you will not get a period. Another point , at your age you should be using the lowest hormone dose possible which is not the NuvaRing since your risk of possible adverse events is slightly higher at your age. I rec. Loloestrin has only 10mcg estrogen- safest dose.
