hi there, be rest assured that consuming iron tablets is not going to make you have a dark skinned baby if you and your husband are fair skinned. Iron tablets are required during anemia
as your baby's requirement of iron is also taken care of by your body so your need supplimentation to take care of the increased demand. Your stools are black as the unabsorbed iron is passed out. I would strongly advise you to continue the tablets for your and the baby's well being. Take care.
