In brief: Short of breath

There are several reasons but primarily the growing fetus is putting pressure on your diaphragm so it sometimes feels difficult to take a deep breath.
You are also carrying more weight than usual so it takes more work. Finally the expanded blood volume makes your heart have to work harder pumping the extra volume.
