Head cold

K
I'm 37 + 6 
I think I have come down with a head cold but I don't have a cough or a fever just a runny nose, a blocked nose and lots of phlegm and this morning woke to a really sore head/headache. I literally never get sick and this is my first 'cold' in like 3 years. And it has to happen this late in the pregnancy. 
I'm worried I'll be sick when baby gets here. 
I'm going to ring doctor today.
Anyone else had the flu or cold this late in pregnancy
