I am in my fourth month of pregnancy and I am going through a severe bout of hot flashes. Is it normal? Can anybody suggest some home remedy?

Taking a sip of cold water with ice usually helps. Also be aware of the foods that usually trigger your hot flashes. If you notice that you get hot flashes after eating spicy foods or drinking caffeinated drinks, best to cut down on those. Breathing exercises also help if the source of your hot flashes stem from anxiety.
