19, Possible pregnancy, Nuvaring, what now?

go to the dollar store they sell tests, not family dollar but like dollar tree, they should only be a dollar, not 3???well, some times you dont have enough hormone for the test to show positive, if you really think you may be pregnant you should stop smoking and drinking, its getting real expensive anyway, and its good for your health to not do it, ive never tried the nuvaring so cant help you with that, but until you get your period id take a test every 3 days or go to the dr and get a blood test✿~☆good luck☆~✿
