Cold/flu before labor?

Samantha
Hi Mommies!
In the last two days I've developed a sudden sore throat, nasal congestion and general "off" feeling. Some cramping and definite pain in back and pelvis. 
When I started researching, I saw that there were a ton of women who said they had developed this up to a week or so before giving birth! 
I'm aware of the "anything can be a labor sign" situation we all have in the third trimester. Just curious if anyone out there has an opinion or story to share on the topic?
