Pregnant or flu?

I'm just gonna list my symptoms.

-excessive saliva production

-extreme nausea/vomiting

-peeing a lot

-lower back pain

-sore throat

-headache

-coughing

-weakness

My period is supposed to begin in 3 days but I never get these symptoms. I usually know it's coming because my breasts will be sore/tender and I'm moody as hell. Haven't experienced that. My bf and I have been using the pull out method.

Anybody ever think they had the flu, but turn out pregnant? It may all just be coincidence, but I have had vivid dreams recently about being pregnant and today everything I saw was about pregnancy and babies...

EDIT: Can't test right now. On vacation. Will be home Sunday, the day my period is supposed to start..
