Welcome to Healthcare Magic,
No any discharge are normal, neither brown nor white. I would advice you maintain strictly perineal hygiene, if some lotions, soap, etc.. cause irritation , avoid them. Mostly vaginal ,persistent discharge occurs due to infectious factor( bacteria, fungus ), and sometime noninfectious (irritant) factor. To clarify you need laboratory investigation ( complete blood count
, urine analysis, pH test , wet mount test , KOH preparation, culture ) and Gynecologist consultation, because your discharge for so long time is not normal condition.
I wish you good luck and speedy recovery,
Hope this helps and I have answered your query.
