Yes you could be, now the waiting for your next cycle begins.

I suggest waiting for your next period. If it doesn't begin when expected, wait two weeks and begin testing. Be aware that emergency contraceptives can affect your cycle for a month a two.

Another suggestion, make an appointment with your doctor to discuss birth control and what your options are regarding this recent event.
