Cold/flu HELP!!

Anyone know how to deal with cold or flu like symptoms while pregnant? I know I can't take medicine right now but any home remedies that can help? TMI I know but every time I cough or sneeze I pee my pants a little and have to change my clothes. I went threw 10 pairs for underwear one day before I realized I should just wear pads to help with staying dry. And I am not for sure if it is a cold or allergies because I have an itchy nose and eyes and can't stop sneezing but coughing just came into play yesterday!! Help!!! Please
