Ok so I'm 22. I've had periods since I was 15. I've never thought much about this and I've never brought it up because I thought it was normal... Every time I start my period, the blood is dark brown. (Lol not from poop) and throughout my period,(usually only 3days, I know I'm lucky) it's mostly dark brown. Rarely red. And also I have super light periods. Ok is this normal?
