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.
If the egg that is released is not fertilized, the lining of your uterus will shed and you will have your period.
