hi, i had my period last october 6-8. after 2 weeks (october 20) i experienced brown spotting. i didn t had sex with my boyfriend yet after my period until now. i am experiencing back aches, urge in urinating 2days ago, stomach cramps, and nausea (bad not that bad) also a little bit breast aches. i m in contraceptive pill 2months ago but not taking it regulary. i had also a polycystic ovary. my menstration is not regular too (except if i took contraceptive pill regularly). what does all this mean?? thanks...
