If a pregnant woman has a stuffy nose with a cold, the first thing to do is to keep warm and not get cold or windy again, and it is recommended that the room temperature is maintained at around 26°C. If the cold is only mild, direct medication is often not recommended and most patients recover in about 1 week. It is also important to take care of regular ventilation during the illness, use a humidifier to keep the room at a suitable temperature and drink plenty of warm water. If the cold is more severe and nasal congestion is noticeable or persists without improvement, you will need to visit a hospital and take appropriate medication that does not affect the foetus under medical supervision.
