I'm planning on going to the doctor this week (I have the appt.) but I sorta wanna be prepared.. Ever since I had an ovarian cyst rupture i've had my period lasting about 5-7 days then it stops and exactly 7 days later it starts again.. they are sometimes heavy and sometimes not. this has gone on for about 2 months.. now there is a brown thick discharge as well with a bitter smell... what's wrong?
