I have only been on using the NuvaRing for about 2 weeks now but I am already having mood swings and extreme irritability. I go to school with all men because I am trying to get into the aviation field and the guys I go to school with have informed me that I have become a super bitch. I did not attribute it to the ring until reading the other post's here. I usually ignore all the immature comments that the guys make but lately I have found myself bickering with them on a regular basis. I have only had sex 3 times since I have been on the ring but each time I had an intense burning sensation on the exterior of my vagina, almost like a yeast infection. The reason that I decided to google the side effects of the ring is because ever since me period has ended I have had a think brownish discharge and cramps every day. I have been wearing panty liners for almost two weeks and this definitely needs to stop. The number one reason I decided to try birth control was because of my severe menstrual cramps, heavy periods and mid month spotting. Now I have all month spotting, what the hell! By far the worst experience I have had since using the ring happened yesterday. As I mentioned before my irritability has definitely increased. That was very evident yesterday when while at work, of all places, I attacked a girl and beat her up. I was arrested and charged with battery. Granted the girl and I have been having an escalating fued for the last couple of months. My mother was also involved and she was more pissed with my mother than with me. But the fight had in no way been physical until yesterday when she began to curse at my mother. I lost it and swung her into the wall by her hair, she never even saw it coming. I sort of blacked out and cant even remember all the events. This whole thing was definitely out of character for me, especially since I was at work. I am fortunate to work at an office where we are all close enough to be called a family. My boss stood by me and did not fire me. He even bailed me out of jail but that is definitely one hell of a side effect
