Dear Casperx2,

Emergency contraception (EC) — also known as the "morning-after pill" — is one of the safest and most effective ways to prevent unintended pregnancy after unprotected sex or contraceptive failure.

EC does not cause an abortion; instead, EC helps prevent pregnancy. EC can reduce the risk of pregnancy when started within 120 hours (five days) of unprotected sex. EC prevents the egg from joining with the sperm. It can also prevent ovulation — the release of an egg. Theoretically, EC could also prevent implantation, but that has not been proven scientifically.

Pregnancy begins when a fertilized egg implants itself in the lining of the uterus. EC prevents a pregnancy before it occurs, and will not harm an already existing pregnancy.

Plan B, a brand of EC, is available over the counter at many pharmacies for women over 18. Teens under 18 can still access EC with a prescription. EC is available at Planned Parenthood health centers, as well as college, public, and women's health centers. To make an appointment call 1-800-230-PLAN for a Planned Parenthood center nearest you.

Many Planned Parenthood health centers have weekend and evening hours to help women get the services they need, when they need them — fast. However, the best way young women can protect themselves is to get EC before an accident happens, and keep it on hand in case they need it. That way, they won't waste time after unprotected intercourse waiting to get an appointment with a health care provider and trying to get a prescription filled.

If started within 72 hours, EC can reduce the risk of pregnancy by 75-89 percent. The sooner it's started the better.

Hope this information helps!

Take care,
