I used Nuva Ring after the birth of my first child in 2003 until I decided to get pregnant again in 2007. I've always had a low sex drive, so I never suspected Nuva Ring could be the culprit, but after reading some of the testimonials, I'm wondering...By the way, after I stopped taking it, my sex drive soared - I was having the time of my life and so was my hubby. We got pregnant right away. I just went back on the NuvaRing 2 months ago after the birth of my second child, which was a scheduled c-section (no harm done to the vaginal area in other words). We've had sex about four times since I started birth control again and it has been extremely painful every time. When I'm not on my period, I'm experiencing a yellow discharge accompanied by some minor irritation. I have been wearing a pad around the clock for literally 3 months! I started bleeding (a period I guess) the day after I started the NuvaRing for the first time. When I called my ob, she said it was a normal side effect of the Ring and to keep it in business as usual until I was scheduled to take it out again in 3 weeks. I bleed the entire 4 weeks until inserting my second NuvaRing. We've had sex twice since and it was almost unbearably painful both times. Now, I am experiencing a yellow discharge again accompanied by some minor itching and discomfort. My ob again said it is a normal side effect but just in case, prescribed a yeast infection med. I completed the course and still have the symptoms. I loved this product and highly recommended it to my friends for the past 5 years - it is so easy! Now I'm wondering if they've changed it over the past year? Plus, the last thing I need is an even lower sex drive.
