So I am a healthy, 23-year-old college student. I started the nuva ring over a week ago -- 10 days to be exact -- and I think it's finally started to click. I have become a PSYCHO. I read all of the pamphlets for the thing, and the only side effect I found related to mood problems was "depression". Well, I have turned into this crying-at-random, bitchy, angry, up and down within minutes psycho person! I can't take this. I have turned MEAN, and I am not a mean person at all. I appreciate everyone who has posted their experiences, because now I know I just need to take this thing out.
