Talk to Gynecologist on Brown Discharge In Periods.

AoA
from your query i am able to understand that you have regular menstrual cycle but you are not having proper bleeding....only brownish discharge.....Thats Ok. keep ur diet healthy...Drink alot of water....and start exercise/ walk if u are not doing already

AoA u means to say that ur periods are regular but just color is brown.
go for cbc to have a look on your hemoglobin n take healthy diet regular exercise..start multivitamins n iron supplements if hb low...thanks
