STD Home > Ogestrel and Pregnancy

If you are taking Ogestrel and pregnancy occurs, you should immediately stop taking the birth control pill. Women who intentionally use Ogestrel (or any birth control pill) during pregnancy could experience serious problems, such as miscarriages or birth defects. However, if you accidentally used Ogestrel before realizing you were pregnant, it likely won't cause any serious problems.

Ogestrel and Pregnancy: An Overview

Ogestrel® (norgestrel/ethinyl estradiol) is a prescription oral contraceptive (one of the many available versions of "the pill"). As with any birth control pill, it is not a good idea to intentionally take Ogestrel during pregnancy. Although it is unlikely for you to become pregnant if you take the drug correctly, your risk of pregnancy increases significantly if you do not take it correctly.
If you miss your period while taking Ogestrel, you may want to make sure you are not pregnant (an over-the-counter pregnancy test should be sufficient), especially if you have missed any pills. If you miss two periods in a row, you should definitely make sure you are not pregnant. Keep in mind that if you take Ogestrel correctly (without missing any pills), the risk of pregnancy is quite low.

Ogestrel and Pregnancy Category X

The U.S. Food and Drug Administration (FDA) uses a 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 occur, such as birth defects or miscarriages. A pregnancy Category X rating is the strongest indication that a medication should not be taken during pregnancy.
Although you may have heard that taking birth control pills during early pregnancy is dangerous, the truth is that doing so probably won't cause any serious problems, even though Ogestrel is a pregnancy Category X medication. Many studies have shown that there is no increased risk of birth defects when birth control pills are accidentally taken during early pregnancy. However, Ogestrel should never be taken intentionally during pregnancy, as there are no benefits to doing this. It should not be used in an attempt to prevent (or cause) a miscarriage, as it is not effective for such uses.
