Possibly: Plan B can change your menstrual cycle, but for peace of mind have a pregnancy test if you missed your period.

Pregnancy test: Plan b could alter the timing of your period. However, you should do a home pregnancy test. If the result is negative repeat the test 4-5 days later unless you get a period by then. Use first morning urine and follow the instructions carefully. If you do not wish to be pregnant, use contraception all the time, every time. Consider implanted contraceptive, or IUD. Wish you good health!
