Anytime you have unprotected intercourse, there is the risk of pregnancy.
Aftter taking Plan B, you may experience some irregular spotting or bleeding. This is normal. Your next period may be earlier or later than usual. It may be lighter, heavier or spottier than usual. If you do not have a period within 3 weeks, do a pregnancy test.
The end of a period is typically a less fertile time for most women, so the chance of pregnancy is lower (but not zero). Additionally, when taken within 72 hours after unprotected sex, Plan B can be up to 80% effective at preventing pregnancy.
