Runny/stuffy nose?

Bethany
On my 6dpo I woke up with a sore throat and stuffy nose. On my 7dpo the sore throat went away but the stuffy nose remained, in fact it's gotten worse now that I'm going into my 8dpo (not to mention lots of sneezing). I've never been prone to allergies so I thought it was weird. Has anyone had a similar experience with this as an early pregnancy symptom?
