hi this is from nuvaring it may help you. some women miss periods on hormonal birth control even when they are not pregnant. consider the possibility that you may be pregnant if: you miss a period and nuvaring was out for more than 3 hours during the 3 weeks of ring use you miss a period and waited longer than 1 week to insert a new ring you have followed the instructions and you miss 2 periods in a row you have left nuvaring (etonogestrel/ethinyl estradiol vaginal ring) in place for longer than 4 weeks if you know or suspect you are pregnant do not use nuvaring. see your health care provider as soon as possible. hope this helps you. good luck
not getting period on nuvaring. i have been on the nuvaring for about 7 months. from what my ovulation calendar says i should have started my period this past saturday (i usually start on sunday). well it is now monday and i haven't started yet. ever since i have been on the nuvaring my period is never consistent. i will get it regular for a few days and the next month i will barley get anything at all. does anyone else have problems like this? is it normal? should i worry about if i'm pregnant or not?
