I started taking glutathione and vitamin C with rosehips 2x a day last february 16.. after a few days of taking it, i noticed i'm having a drops of brown discharge but it just come and go. My last monthly period was january 20. So i was expecting my next period last week. But instead of period, i am having brown and pink discharge for several days already. And i am a week delayed now. Is this normal? Does the supplements i am taking affects my cycle?
