question: I am currently using Nuvaring. I accidently left it in one week too long, taking it out on day 28 instead of day 21. On the 28th day my husband and I had sex. I usually start my period a few days after I remove the nuvaring but I havent had any spotting. I am concerned that I may be pregnant, a hope pregnancy test said I was not pregnant. With having the nuvaring in one extra week, am I still protected with birth control?
