Whether it is concerning for a pregnant woman to have blood in her stool depends on the specific circumstances. If the bleeding is due to constipation caused by poor dietary habits, and the amount of bleeding is not significant, adjusting the diet may improve the condition, which likely indicates a less serious situation. However, if the bleeding is caused by hemorrhoids, with substantial blood loss during each bowel movement, this may be more concerning, as excessive bleeding can easily lead to anemia.
