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 you start a new medication while you are taking birth control pills, check with your doctor or pharmacist to make sure that it will not reduce the effectiveness of the pills. Use a back-up method of birth control, such as latex condoms and spermicidal foam or gel, until you can check with your doctor or clinic.
