Here is some advice on colds and flu while pregnant from MedHelp.org and the I'm Expecting app. There's also a link to medically reviewed advice from an ob/gyn on over the counter medicines that are safe in pregnancy. You'll find these in Week 10 and Week 20 of the app.

Warm tea with honey will help soothe your throat.
I'm very skeptical about taking mess while pregnant even tho they are safe! I had a sore throat a couple weeks ago, make some hot tea with honey and lemon! Works wonders, and drink lots of orange juice, vitamin c fights off any infections
