Does Accutane affect the menstruation cycle for women?

April 5, i started taking 20mg of accutane but doctor prescribed me 10mg after breakfast and 20mg after dinner, the first time i take accutane i was on my 3 day of my period. April 29 i saw the blood so i think my period arrived on that day but the next day its stop but i saw brown discharge. Does accutane affect the menstruation cyle for women? Is it normal, because its my first time to experience this kind of situation.
