If i stared nuvaring the 31st of march for the 1st time and my period usually comes around the 3rd or 4th would nuvaring make it not come that quick?

It'll be late: The NuvaRing will most likely prevent you from getting your period until you take it out about 3-4 weeks later.

Yes: Starting the NuvaRing at that time could delay and alter the length of your period. Usually you would wait for a period to begin your first cycle of nuvaring, but you haven't caused yourself any harm. You should get a period after you finish the 28 days of this cycle and remove the ring. It's a good birth control method. Finally, make sure you are not pregnant with a good urine pregnancy test.
