8. Stuffy Nose
Another unusual sign of pregnancy is nasal congestion. Many women report waking up with plugged noses and then having to blow their nose frequently throughout the day. This change is caused by the mucous membranes in the nose being extra swollen.
When the mucous membranes swell, they tend to dry out, which can lead to the nose bleeding. Because more blood circulates throughout the body during pregnancy, the blood vessels in your nose are more susceptible to swelling. This condition is known as pregnancy rhinitis and affects up to 30 percent of expecting mothers. Typically it starts during your first trimester and can get worse toward the end of your pregnancy. Women with pregnancy rhinitis will usually get rid of their congestion within two weeks after giving birth.
