We do use low doses for some women with recurrent miscarriages and clotting abnormalities, so if your provider suggests it, be sure you understand why. Some studies have even suggested that it's not the medicines that are the problem alone, but that women with seizure disorders may have a higher risk of birth defects in their children. Many women who have been free of seizures for several years may be able to safely stop taking medication, but do that only with physician guidance. It's best to stop anti-epileptics before getting pregnant. That way if you have a problem you can get back on them before getting pregnant.
Some people get pregnant while on the pill, usually because they missed a few.
If you took the pill before you realized you were pregnant, don't worry. It has not been shown to cause birth defects. Next week I'll talk more about medications in pregnancy.
