On Sunday I had this wierd brown discharge only once that day I thought I was gonna have my period but no, yesturday same thing happend & today again but this time with blood not like my normal periods this is way less and only happends when I use the bathroom & wipe. What can this be?? (my parents don't know yet by the way:/)
