Overview

Although the majority of pregnancies are uneventful, sometimes complications do happen. The following are some of the more common pregnancy complications.

Too much or too little amniotic fluid in the sac around the fetus may be a sign of a problem with the pregnancy. Too much fluid can put too much pressure on the mother's uterus, leading to preterm labor. It also can cause pressure on the mother's diaphragm. This can lead to breathing difficulties. Fluids tend to build up in cases of uncontrolled diabetes, multiple pregnancies, incompatible blood types, or birth defects. Too little fluid may be a sign of birth defects, growth retardation, or stillbirth.
