"i been on nuvaring for 6 months and just recently i been feeling really depressed, crying for no reason, and accusing my boyfriend of cheating. i&#039;m just been really moody and not really want to do anything.  could it be a mood reaction from it ? i need help so i could switch to a new birth control. it only happens 1 week before i have to take out the nuvaring and when it&#039;s out that whole week i just become a disaster."
