Runny nose an early pregnancy symptom?

Kari • Hi! Kari's the name. Preggo with my second bundle of joy! Love muffin #1 was born March ‘17. 👶🏻
I'm four weeks pregnant and for the last two weeks, I've been constantly blowing my nose.   I've already gone through four boxes of tissues.  Is this a random symptom?  I'm not sick or suffering from allergies, just closing my nose throughout the day.   
Thanks for your help!
