okay so I haven t had a real period since march 6, 2015. So on june 11,2015 i started spotting real lightly old brown blood, i thought to myself cool, this must be my period. Well I m pretty sure I m wrong. I m still bleeding. Its been going back and forth from brown to red, then next day it will be brown again. Well my question is...why is this happening? Its not a heavy flow either its very light. Is this normal?
