What are the chances im pregnant?

I was on the NuvaRing took it out for the week of my period then left it out for 2 weeks AFTER the week i had my period . I put it in on Friday around 4pm then i had sex the next day around 2pm so my Birth Control was only in for about 24 hours , is it like having unportected sex because it was only in for 1 day when you suppose to leave it in for 7 in order for it to work , i know it was stupid so i don't need to hear that . Im just wondering how high the chances are of me being pregnant , i did not use a condom either and i had sex about 5 days before my expected period (Saturday) my period is suppose to come Thursday . i hope someone can help me because im worrying .
