I was on birth control pills for about 12 years when I decided to stop taking them about three months ago. For the past two weeks I have been experiencing some hair loss so I made an appointment w/my MD and she said that hair loss can occur when stopping hormones and she suggested Nuvaring. I didn't even have the thing in for 24 hours before I took it out! My head hurt so bad I thought I was going to die! I also got extremely queasy and sensitive to the smell of food so much that I couldn't be around my coworkers heating up their lunch. I had to give a presentation and felt the whole time that I might throw up in front of everyone. I also became extremely irritable and was ugly to a patient I saw that day and yelled at my husband for no good reason. My head felt like it was in an awful fog and I felt like I couldn't think clearly. I never experienced anything like that on BCP's. I will NEVER try Nuvaring again. It was awful. I'd rather keep losing my hair and go bald then take Nuvaring!
