If there is blood in the nose in the eighth month of pregnancy, the increase in blood volume of the blood vessels of pregnant women at the end of pregnancy will lead to dilatation of the surrounding capillaries, and rubbing the nose or blowing the nose frequently will easily lead to the rupture of blood vessels in the mucous membrane of the nasal cavity and cause bleeding, which is usually not very large and most of them can be stopped by themselves. If the bleeding is more urgent, it may be accompanied by active bleeding spots, so you should go to the hospital for examination. If necessary, you can ask the doctor to stop the bleeding by pressure or use laser to weld the bleeding spots; if the bleeding is more frequent or even if there are signs of anemia, you need to do routine blood tests and coagulation tests to rule out blood problems.
