What causes a change in a platelet count when pregnant?

In brief: Increased red cells

The amount of red blood cells in the pregnant woman's blood increases, so she can better supply oxygen to the growing fetus.
When the red cell "mass" increases, more plasma is added also. However, the platelets fail to keep up, and are relatively less.
