What are the symptoms of pregnancy in the fifth month?

People usually feel fetal movements for the first time during the fifth month. It may feel like flutters or butterflies in your stomach. This is sometimes called quickening.

The pregnancy symptoms of the fourth month continue this month. Heartburn, constipation, breast changes, dizziness, shortness of breath, nose bleeds, and gum bleeding are common. Your breasts may be as much as 2 cup sizes bigger by now.
