Hi Anonymous,
It is a know side effect that taking emergency contraception can mess up your menstrual cycle. If you are concerned, make an appointment to see your doctor, otherwise, you will just need to wait until you get your next period. Be sure to not put yourself at increased risk for pregnancy until then, and using regular birth control methods (condoms, spermicide, birth control pills, etc.) will alleviate any worry in the future. Pregnancy tests are very sensitive at picking up pregnancy hormones, so if it says negative, you likely are not pregnant.
