"i&#039;ve been on nuvaring for several years and i absolutely love it. i insert a ring every 3 weeks for 3 months then take it out for 1 week to allow a period. this is what my doctor suggested and i was all for having only 4 periods a year. the only side effect i have are mild leg cramps that motrin can take care of. this is a very effective birth control. it does become a little hard sometimes to insert or take out the ring but you can always have your partner help you."
