Fever in the first month of pregnancy has little effect on the fetus. You can drink more water, pay attention to rest and take vitamin C supplements to prevent cross-infection. If the fever is caused by wind-cold cold, you can use ginger, white onion and brown sugar, decocted in water and drink in place of tea, which has the effect of dispersing wind and cold and generating sweat, which is beneficial to the recovery of cold and temperature control. If the fever is caused by wind-heat cold, you can take a decoction of rhizome, scutellaria, forsythia and maitake with water and drink it as a substitute for tea, which has the effect of clearing heat and lowering temperature. You can also take oral Chinese medicines, such as Pu Di Lan Anti-inflammatory Oral Liquid and Blue Scutellaria Oral Liquid to clear heat and detoxify the toxins. If the fever persists and is accompanied by coughing and wheezing symptoms, it is recommended to visit the obstetrics and gynecology department. When choosing the medication, you should choose the one that does not affect the fetus and the pregnant woman.
