What causes nosebleeds and bleeding gums in pregnancy?
Your blood flow increases so much during pregnancy that sometimes it overflows. Your gums and nasal membranes are two places where blood may appear unexpectedly. Your gums may bleed when you brush your teeth, but unless pain or redness is present, this isn't something to worry about. Nosebleeds are also very common during pregnancy, particularly when you blow your nose. You may also notice that your nose is more congested than usual, also a result of increased blood flow to the mucus membranes.
