Birth Control

Alright I'm a little bit worried because it was my sugar pill days for my birth control and then I took my pill to start my month over and had sex without a condom that night (technically the next day it was 4 am) and had sex without a condom the next night too. But I've taken my birth control everyday since my new pack started again. I don't get a period using my birth control so I wouldn't know if I was pregnant. I was just wondering if I should worry about it or just relax?
