Girls with PCOS typically have irregular periods which means they may not ovulate (make eggs) on a regular basis. Most girls/women with PCOS ovulate some of the time though and many get pregnant. When you are ready to start a family, you can talk to your health care provider about whether you would benefit from taking special fertility medicine to help you ovulate. In the meantime, if you are sexually active you should always use a birth control method and condoms to prevent an unplanned pregnancy and sexually transmitted infections.
