It was red like it usually is but 3 days later I started again it's lasted 4 days already so far and it's brown. I also have the cramps and stuff like I usually do but this has never happened before.what could be the cause of this? My Tubes are tied so I know it has nothing to do with pregnancy. I'm 34 yes old and have been getting hot at night when I go to bed.this isn't normal for me either I'm always cold and hogging the blankets but for 3 weeks now it's air on, fan on and no blankets.whats wrong with me?
