Treatment for cough and cold

15 weeks pregnant here. My work is always infront of a computer meaning my surroundings should always be centralized. My colleague had a flu for 5 days and went back to work even if she's not yet well. Now, I have runny nose and a very dry cough. I feel like I have a fever but whenever I check my temperature, it's normal. What should you recommend me to do or to drink?
