I got diagnosed w adenmyosis. Last week on 19th I had bright red blood some slime 2 it w a tint of light pink. Last for a few days and then turned 2 a light to medium brown blood. 9 days later I had a different color discharge. During this time I have had abdominal pain lower and some upper and left side hurts a heavy feeling. I'm now also getting slight lower back pain and slight burning feeling in left lower abdomen. What could be my cause ?
