Nosebleeds and nasal stuffiness are common during pregnancy. They are caused by the increased amount of blood in your body and hormones acting on the tissues of your nose. 

What might help: 
•    Blow your nose gently. 
•    Drink fluids and use a cool mist humidifier. 
•    To stop a nosebleed, squeeze your nose between your thumb and forefinger for a few minutes. 
Call your doctor if nosebleeds are frequent and do not stop after a few minutes.
