I've had very dark green stools for the past three days and I am a little bit constipated. I do not have any abdominal or pelvic pain. There is no blood in my stool. The only changes that I have made on the past 3 days is that I have been watching what I eat and also the amount. I take Methyldopa, Hydrochlorothiazide, levonthroid, pre-natal vitamins, lupron injections, and Estrace pills. The only new medications that I just started taking is the pre-natal vitamins and the Estrace pills, but I did not have the dark green stool when I took them in the past. I also had diverticulitis 2 yrs ago. The only surgerie that I've had is a laparoscopy to check my fallopian tubes. The only other change that I have noticed is that I have been under an extreme amount of stress these past three days
