Stuffy or bloody noses are quite common during pregnancy and usually don't subside until after giving birth.
What is the reason of this?
While your stuffy nose may be the result of something unrelated to pregnancy, such as allergies or a sinus infection, many expectant mothers experience nosebleeds for no reason alongside their pregnancy condition. As the pregnancy hormones estrogen and progesterone move through your body, they accelerate blood flow and soften your tissues. This can cause your blood vessels to narrow, causing congestion and bleeding.
Tips
If congestion is a factor in your pregnancy as opposed to allergies or similar, be prepared long-term. The blockage is unlikely to disappear before you give birth, but there are different things you can do to manage it. Adding Vitamin C to your diet and a humidifier to your room can help deal with congestion.
