Thank you for posting your question here, I will try to answer it to the best of my abilities.
From what I can tell you arent using it right, you're supposed to keep it in for three weeks and then take it out for one week during your period.Nuvaring
doesnt stop periods, it is merely a contraceptive
method which is somewhat similar to how birth control pills work.
As such, from now on, use it for three weeks, then pull it out for one week during your period and then once your period is over, place a new one.
I hope this answered your question.
