Worried!

Adrina

I started nuva ring 2 days after my period ended. My bf could not wait the full 7 days for not having to use condoms, so we had sex like 1 day before my ovulation window and used pullout method. Within 12 hours I took plan B as extra precaution. Should I be worried about pregnancy? My cycle is 21 days long I'm expecting my period in 10-12 days.
