Mircette and Pregnancy

You should not intentionally use Mircette during pregnancy, as it may cause serious problems (such as birth defects or miscarriages). Due to these risks, the FDA has classified Mircette as a pregnancy Category X medication. However, taking the birth control pill before you realize you are pregnant will probably not cause any problems. If you are taking Mircette and pregnancy occurs, you should immediately stop taking the contraceptive.

An Overview of Mircette and Pregnancy

Mircette® (desogestrel/ethinyl estradiol) is a birth control pill, known medically as an oral contraceptive. As with all oral contraceptives, Mircette should not intentionally be used during pregnancy. Although it is "common knowledge" that taking birth control pills during early pregnancy is very dangerous, it is unlikely that it will cause any serious problems if you accidentally take them before realizing you are pregnant.

Mircette and Pregnancy Category X

The U.S. Food and Drug Administration (FDA) uses a pregnancy category system to classify the possible risks to a fetus when a specific medicine is taken during pregnancy. Pregnancy Category X is given to medications that should not be used during pregnancy, usually due to the serious problems that could potentially occur (such as birth defects or miscarriages).
Even though Mircette is a pregnancy Category X medication, it will probably not cause any problems if accidentally used during early pregnancy. Many studies have shown that there is no increased risk of birth defects when birth control pills were accidentally taken in early pregnancy.
If you miss your period while taking Mircette, you may want to consider making sure you are not pregnant (any over-the-counter pregnancy test should be sufficient). If you miss two periods in a row, you should definitely make sure you are not pregnant. Keep in mind that if you take Mircette correctly (without missing any pills), the risk of pregnancy is quite low.
If you accidentally used Mircette for a while before you realized you were pregnant, it probably will not cause any problems (although you should discuss this with your healthcare provider). If you are pregnant, you should stop using Mircette right away. If you think you may be pregnant, you should contact your healthcare provider for further instructions.
