For the most part, taking birth control while pregnant will not cause your baby any harm. This is especially true if you have been using birth control pills early in your pregnancy. But, if you have an IUD and become pregnant, you may be at risk for certain pregnancy complications.
Birth control is only 99% effective. Which means that 1 in 100 women will get pregnant while taking birth control as directed. Other things can affect your chances of conceiving while on this pill, like missing pills and taking antibiotics. It's unlikely to get pregnant while you're on your period-but not impossible.
