Hi there! I've been using the Nuvaring for 3 months now and haven't taken any breaks (keep it in for 4 weeks and just insert the next one right away). For how long can I do that? A doctor recommended at least taking a break 3-5 times a year. Is anyone here using the Nuvaring constantly with a break every few months? And then for how long? And also, if I already have the ring in for few days, can I take it out for 7 days and put the same ring inside? Or is it ineffective if I take it out?
