Common cold while pregnant

I traveled last weekend and I think I caught a cold while traveling. I've had a sore throat, cough, and runny nose. I sucks on top of other pregnancy symptoms :( Im only about 6 weeks pregnant. It's hard for me to sleep because I'm stuffed up and during the day I feel pretty shitty. Does anyone have any good pregnant cold remedies? I know we can't take Advil, but does any other medicine work while pregnant? Thanks!
