While constipation is common during pregnancy, I have found that pregnancy tends to ease other intestinal ailments, including Irritable Bowel Syndrome. So patiently observe how your body responds to pregnancy. If constipation seems to predominate, consider changing your prenatal vitamin to one with a stool softener. If diarrhea predominates, you can treat it with Kaopectate® only when it becomes incredibly annoying and persistent.
Finally, if you plan to nurse, don't take dicylomine, as it has unpleasant effects for the newborn.
