10 weeks pregnant and feeling sick, what could this be?

I am 10 weeks pregnant and for the last 3 or 4 days have been feeling sick. It started as a cough, then a really runny congested nose, then sneezing, and now I'm having a hard time breathing. I was trying to blow dry my hair but I could only dry a few pieces before I was winded and needed to sit down....someone please tell me this is just a common cold.....if not, what else could it be?
