This condition is commonly caused by dry air in the room, resulting in bleeding caused by the erosion of the mucous membrane of the nasal cavity, which is usually not very large and can mostly be stopped by itself. Another condition is that when pregnant women reach the end of pregnancy, the blood volume of blood vessels increases, so it will lead to local dilation of small blood vessels. The main thing is to pay attention to rest, avoid strenuous exercise, take appropriate vitamin supplements, and then you can use some nasal mucosa lubrication drugs, such as peppermint paraffin oil drops. Then you can use saline or physiological seawater for nasal rinsing to improve this symptom.
