[|Human|] so i have been on nuva ring for almost a year now...this past month i became sick and was prescribed a z-pac. My boyfriend and i were having sex (the first day of my period) and the condom broke, some of his sperm was inside me... what do you think is the likelyhood of getting pregnant? should I even be worried?
[|AI|]  Hello, and I hope I can help you today. The Nearing used alone is greater than 99 percent effective in preventing pregnancy. Many women use it without a backup method of birth control. In addition, because the Nearing is absorbed through the skin of the vagina, its effectiveness it is not reduced by antibiotics because the medication is not swallowed, so it is not metabolized in your liver like oral birth control. In addition, the majority of women do not ovulate during their menstrual cycle even off birth control. So I really do not think you are at risk of pregnancy in your situation. I hope I was able to answer your question and that this information was reassuring. Best wishes,
