If you have a cold in the second month of pregnancy, just a mild runny nose or sneezing, it often does not affect the fetus. It is recommended to drink more water and eat more fruits to increase the resistance, and the symptoms of the cold will disappear. However, if there is a severe fever or a combination of other symptoms, such as pneumonia, it may affect the fetus. A high fever may lead to miscarriage, so if this happens, go to the hospital as soon as possible to get the appropriate tests, have blood drawn to find out whether it is a viral or bacterial infection, and give active treatment. It is also advisable to drink plenty of water during the cold, as this will also relieve the symptoms of the cold. During pregnancy, the body’s resistance is relatively low, so it is recommended to go to public places less often to avoid the transmission of influenza.
