Family Planning Plus

Yes, you could have become pregnant while having unprotected intercourse. If you were not taking the birth control pills, then you were not protected. Plan B helps prevent pregnancy by delaying ovulation. It is most effective when taken within 24 to 72 hours after unprotected sex, but may be somewhat effective when taken as long as 120 hours after unprotected intercourse. Neither Plan B nor the “regular” birth control pills affect an already existing pregnancy. They do not harm a pregnancy or cause a termination (miscarriage).

Continue taking your birth control pills every day. If your next period is more than 1 week late, do a pregnancy test. Be sure to begin your next pack on time. If you cannot begin a new pack as scheduled, use condoms or abstinence until you have taken the pills for at least 7 consecutive days.
