Comitted symptoms and conditions

I had been using the nuvaring for a year when I started noticing side effects. At first I thought it was just me adjusting to a new partner, or that it was a yeast infection. But then it returned at the same time during each of the next three months. A few days after I took it out, the skin of my vulva would become sensitive and itchy, somewhat swollen or red, and it became difficult to use my keeper (a healthy alternative to tampons). But a few days after the ring went back in it would go away, only to return again. Well, my skin became so sensitive, that my vulva actually tore- almost an inch gash- when I was having sex with my boyfriend and blood was everywhere. I promptly went to my gyn, who had no immediate idea as to the cause of this sensitivity. There are a few possible skin conditions, such as lichen sclerosis, but the thing that stands out is that it happens at the same time each month. My Gyn also said that lack of estrogen can cause the vulvar skin to thin, which would make sense then since it happens when the ring comes out. Perhaps, she said, my body has stopped compensating by creating its own estrogen when on the nuvaring, and the nuvaring is not an adequate replacement. Anyway, its a possibility that the problem is unrelated. i am going for a biopsy tomorrow. But have already comitted to never using the Nuvaring ever again. And my boyfriend is totaly supportive of leaving hormonal contraception behind!
