On 29th may i had very light bleeding that lasted for 2-3 days after taking an ipill. i have pcod for which i take krimson 35. the last time i got my period was on 10th may. i've been taking krimson 35 but not properly, missing a few doses, taking pills at 12 hour gap to make up for missed dose. it's the seventh day since the krimson 35 slip finished and i still haven't gotten my period. there is only brown discharge and i get period-like cramps. i've taken several pregnancy tests which all came negative. what could the problem be?
