Anytime you have unprotected intercourse, there is the risk of pregnancy. The more often you have unprotected intercourse, the more likely it is that you will become pregnant.
Plan B is an emergency contraceptive. When taken within 24 hours after unprotected intercourse, it is about 75% effective at preventing pregnancy. Plan B contains a dose of hormones that helps prevent pregnancy by delaying ovulation. It is “good for” one sexual encounter. It is not a long term method of birth control and does not offer any extended protection. Additionally, because it delays ovulation, frequent use of Plan B may actually increase your chance of pregnancy.
If you and your partner are not planning a pregnancy, consider using condoms. If your partner is not open to using condoms, then Plan B is your option. You may want to consider beginning a long term method of birth control like the birth control pills or DepoProvera injection.
