Questions about fighting a cold while pregnant.

I started having a slight cough and congestion on Thursday.  I was hoping it was just allergies.  My symptoms have gotten worse every day.  Yesterday my cough was extremely mucousy.  I slept horribly last night.  Had pains in all of my sinus cavities on the right side of my face (throat, nose, eye, head).  Now today my cough is dryer but I can barely breath out of my nose.  I know sudafed, tylenol cold, and robitussin are all okay to take.  Should I try to ride it out by taking those to see if any works or should I go to my doctor?  I don't have a fever but am thinking the way things are going I will have one soon.  Is it very dangerous to have a cold while pregnant?
