Girls, hello everyone! Who is sick or has been sick on my period? I have an ear, throat, and nose. Yesterday the temperature was 37.7 today it's already normal, what should I do? I just arrived from Russia, I don't know whether because of the weather or for some other reason, I got sick suddenly, terrible weakness.... I am taking paracetamol children's, gargling with water, Aqua Maris, drinking more fluids. What else can help?
