Since new year's been sick on and off

I keeping getting head colds on and off. Stuffy nose, cough, sneezing, body feels down.

Well cold started yesterday with basically what I stated above.. well last night at 3 am I started shivering out of no where and got a low grade fever at 99.7 took tylenol and it went away..

Getting a fever worries me especially being 31 weeks pregnant...
