This is so interesting. I have been taking NuvaRing for over a year now, and for about a year I absolutely loved it. Recently, however, things have changed. In Feb. I accidentally left the ring in for one week too long and then put it in one day late... I didn't think much of it, but then in March my period was really light. In April, my breast began to swell and got very tender and I started having headaches and a lot of nausea and I started gaining weight. At the end of the month, my period was just spotting. I, of course, took a pregnancy test, which came out negative. In May and June things have continued to be bad...spotting periods, extreme fatigue, a lot of weight gain, constipation, bloating and pain in my abdomen during sex. I took two more home pregnancy tests and even went to my doctor for a blood test...all negative. Today, my family doctor suggested that it could be my nuvaring. I had no idea! That's why I googled NuvaRing side effects today and found this sight. I've scheduled an appointment with my OBGYN so I can change my BC method. Looking back, I have noticed that I am much more aggressive than I was 1.5 years ago. I used to have great relationships with my students and used to be such a patient person, but over last 1.5 years I have started to get aggravated really easily...I even honk my horn at people. That is really not who I am! So hopefully after I take the NuvaRing out, I'll go back to being myself and feeling healthy.
