Constipation or diarrhea

Hormonal changes in early pregnancy can cause your digestive system to slow down. This can cause constipation. Prenatal vitamins can add to this problem as the iron contained in them is also constipating. Adding more fiber to your diet and drinking extra fluids will help with this. Some women, however, will notice the opposite problem, diarrhea although, this is an uncommon early pregnancy symptom. Hormones sometimes affect women differently though. While most women will have issues with constipation during early pregnancy, some will have diarrhea instead.
