Hormonal imbalance: Plan B could disrupt your menstrual rhythm. If at three weeks after your episode of unprotected sex, you do not get a peiod, 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 for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex if you have sex.
