The month of February is short so you put a new nuva ring in 3 days after you took the old on out will that mess up your period?

Ack! You're scaring me! You should be putting in a new nuva ring exactly four weeks (28 days) after you took out the old one! I'm worried that you're doing something like changing it on the 28th of each month. That approach will put you at increased risk for pregnancy in the long months (January, July, August, October, December). Please call your health care provider today for retraining on proper use of Nuva Ring, and on any steps you need to take to reduce your risk of pregnancy.

On the other hand, putting in a Nuva Ring early does not increase your risk of pregnancy, so, if this was the first time you did it based on day of the month and not number of weeks, you are not at increased risk.
