The hormones found in birth control pills are not harmful to a fetus in the prescribed dose. The purpose they serve is to prevent you from ovulating and therefore preventing you from being able to get pregnant. If your menstrual cycles are typical and regular ovulation and the ability to conceive would occur approximately 14 days after the first day of your period. Unless you happened to have unprotected sex at this time, and then for a lot of women even if you did, you probably are not pregnant. Until you know for sure due to a missed period or positive pregnancy test you should continue taking your birth control pills to prevent you from ovulating and getting pregnant. If it turns out that you are already pregnant from that one time the pills won't have hurt the baby at all.
