Constipation is a common problem during
pregnancy. Delayed passage of bowel contents (slow transit) is the most common

Medicines, such as antacids, iron supplements, or

bowel movement and may make the toilet water bloody. It is not serious if
there is only a small amount of blood and if the bleeding stops when the
