Hello, I have gone through your query and appreciate you for the concern. Paracetamol has not been shown to have any adverse effects when used during pregnancy. It is true that it is always better to avoid any medication during the organ formation stage of a pregnancy. Fever is more harmful to a very early pregnancy than the medication used to control it. So, please do not worry; your doctor is doing the right thing. Ask her to take more liquids, easily digestible food and rest in bed. Hope you find this information useful. Take care.
