Thanks for the query.
Since you have missed a period, with a history of unprotected intercourse, kindly do a urine pregnancy test to confirm pregnancy.In case it is negative, wait for your cycle till a week, if it does not resume,, see a gynecologist for medications to resume the cycles. In case it is positive, consult the doctor for termination methods if you wish to, never attempt a termination on your won as it can cause complications. the emergency contraceptive can lead to failure and cannot prevent a pregnancy 100%.
Hope this helped.
