I already had an ipill within less than 18 hours of sex while on medical. However, I also have PCOS issue and my last actual period was on 22nd November 2016 after which I saw spotting for a couple of time with a gap of 8 days each until 22nd December. Also, I have not not got my period with the normal flow after 22nd November. So jus to be sure if I am missing my period cz of PCOS or if the ipill has worked or not, how long do I wait for the period to happen considering the dates and irregularity of the period? I just want to be sure I am not pregnant.
