If you have sex while on a 7- day break from nuvaring, can you get pregnant?

Doubtful . Cycles can be irregular whenever you start or stop hormonal contraceptives. Use a back-up method (condoms) if you do not desire pregnancy and usually cycles normalize by the 2nd or 3rd month. Take Folic Acid if planning to conceive & remember, you can always take a pregnancy test if you are unsure. Take care.
