Hello and welcome to HCM
Your problem is absence of periods for past six months and light brown discharge.
You have been experiencing pre-menstrual symptoms also and there is a mention of cystic ovaries.
These symptoms seem be features of polycystic ovarian syndrome
PCOS is a condition in which there is absence of menstrual cycles due to inability of ova to mature.
However, certain investigations are required to confirm the diagnosis and thus strart the treatment.
Consult a gynaecologist for investigations like pelvic ultrasonography
, LH/FSH levels and testosterone
Thanks and take care
