If you had intercourse on day 3 of your period, it is unlikely that you became pregnant. If you normally take your birth control pills correctly and consistently, then your protection will continue to be effective during your period. The pills that you take during your period are placebo pills. This means that the pills do not contain any active hormones. Most pill packs are set up with 21 days of active (hormone) pills and 7 days of inactive pills. This set up serves as a reminder to take your pill every day, and keeps you on track for starting a new pack.
Missing or being late with a placebo pill will not decrease your protection. Keep in mind that missing or frequently being late with your active pills will decrease your protection. If this occurs, make up the missed pill, and consider using condoms for the next week or so.
