I have been on ortho tricyclin lo, and then tried Yaz, and now i have been on nuvaring for three months. The only weird thing that I have noticed is that there are times when I feel my mood completely change. My boyfriend even notices, asks me about it, and then I have sudden urges to cry. I am a nurse, and even cried on my way into work today. Not sure if this is because of the nuvaring. As for those that have no sex drive, I have one, and on the other pills was so dry. But with this, I actually noticed that it helped with the dryness. Anyone cry all the time like i do?
