I had a cold in early pregnancy before and I've started to come down with one now but what I do is take extra vitamin C and I also get vitamin c cough candies because there are many you cannot take. It's best just to go with a regular vit C kind. And I drank lots of warm water with honey and lemon in it. Surprisingly it all helps really quick. Also, gargle with salt water or even a mouthwash to keep the bacteria from growing in your throat. It'll help a ton!
