Your cycles may get disrupted for a while when you take the emergency pill as it contains high doses of hormone. It is not necessary that every one using the pill should get the withdrawal, some may not. If you do not yet have your normal period even after two weeks it is due, you should see your health care provider for further support. Meanwhile, you may take the blood or urine test for pregnancy
if you want. Emergency pill is more effective the sooner it is taken after the accident. Please reserve the use of the emergency pill for rare occasions in future and practise some regular method of contraception
. Good luck.
