Hello doctor my LMP was 9th August, i had protected intercourse on 16th, however because there was some unprotected contact without any ejaculation i took an ipill to be on a safe side. Yesterday that's 7th September i was supposed to get my periods, however there was only some brown discharge even today I'm only have little brown discharge no proper period like flow, i also suffer from pcod so my cycle length varies however since last 2-3 cycle the length was 30 days, should i be worried about pregnancy? Or will my period eventually start. Kindly help
