Unfortunately, pregnancy is still possible, but you did reduce your risk by taking Plan B. Plan B works best when it is used within 24 hours of the unprotected sex, but it can have some preventive effects when taken up to five days after. Also, since the sexual intercourse occurred just after your period, pregnancy is unlikely since you probably have not ovulated yet.
The only way to know for sure if you are pregnant is to take a pregnancy test. If you miss your next period by a week or more, take a test. If it is negative, repeat the test every two weeks until you either have a normal period or a positive test result.
Plan B should not be used as a regular method of birth control as it is less effective than other methods. If you are going to continue to have sexual intercourse, you may want to think about using a regular form of birth control.
If you live near one of our offices, please call us for an appointment. We serve women of all ages and incomes. We can talk with you about all of your birth control options and help you choose one that best fits your lifestyle. If you live further away, contact the Family Planning or Planned Parenthood office closest to you.
