my period has been abnormal about 5 months now and im starting to get scared. my last normal period was in july. it skipped august,september, october.i went to the clinic in november to take a pregnancy test to see if i was pregnant but i wasnt. shortly after that i finally got my period. it was still abnormal because i was spotting for about a week before it all came down. now it skipped december and i 've just been spotting for weeks now. i almsot though i had a period at one point but now it just went away. my i'm gonna make an appointment to go to the doctor but i just want to know do you have any ideas what this cause may be? my bf think i might have something called PCOS. i know im not pregnant because the doctor says its impossible to bleed while your pregnant unless its implant bleeding which is not a period
