Q. Since being pregnant, I have found that I am far more susceptible to colds and flu that are going around. While I understand it’s from a lowered immune system, I would like to know if there is anything I can take safely for cold symptoms other than a humidifier and Vicks Vapour-Rub. I am very nervous about venturing into over-the-counter medications; however, I am losing a lot of sleep and am in some discomfort too.
