you really shouldn't worry about getting pregnanat while on birth control. your periods are being missed because of the birth control however that is completely normal. i would not be concerned with it at all
i don't have periods due to taking nuvaring. how would i know if i was pregnant since i don't have any periods to miss? . the last two times i put the nuvaring in i put it in a day late. i have pregnancy symptoms and am wondering how soon i can take a pregnancy test for it to be accurate. i know you normally would take one several days after a missed period but i don't have periods.
