I've been on NuvaRing for the past year. I didn't associate all what I was going through with my birth control. To start off, I fell into a terrible depression almost immediatly. Barely getting out of bed, tired all the time. Next, the mood swings came. I turned into a different person. My boyfriend said I've changed over the past year into someone he doesn't even recognize. Constant crying, anxiety attacks and constantly sick. I mean I've had a cold since I've had this freaking thing in my vagina. I thought I had a food allergy or developed some sort of allergy. Just yesterday, I started doing research and EVERYTHING people have been saying about the negative side effects fits me. I also have gained 40 lbs since last April when I started it. I have felt like I have been living in another person's body for a year. SO, good luck to all of you who are sticking with it....
