Hi!
I can't advise you what to do, but can tell you what I would tell my own patient, and encourage you to call your own doctor.
Because you took the emergency contraception, your cycle is going to be somewhat unpredictable for awhile. I would suggest testing for pregnancy weekly until either the test is positive or the period arrives.
I would also strongly advise you to consider some reliable form of contraception unless you want a baby!
Good luck!
Dr B
can a doctor please advise me
