Orange menstrual blood

about 4 years ago I had orange menstrual blood and I never got it again well recently I’ve been very weak and sick I just got 5 tubes of blood taken today while I’ve been on a heavy period and hadn’t ate anything today, also take aspirin a lot this month cause of headaches. The doctor thought I was anemic and now my blood is orange and brown today on my 3rd day of period would anemia cause this?
