Anytime you have unprotected intercourse, there is the risk of pregnancy.
Plan B helps prevent pregnancy by delaying ovulation. It is not a long term method of birth control, nor is it effective for multiple acts of intercourse. After taking Plan B, your next period may be a little earlier or later than usual. However, depending on when your last period was, there is a possibility that you became pregnant on the 16th. If your next period is more than 1 week late, do a pregnancy test.
Consider using condoms consistently or starting on a long term method of birth control. When used correctly, condoms, birth control pills, and the DepoProvera injection are all very effective at preventing pregnancy.
