AF 2 Weeks Late BFN HPT- Question

I've literally never missed a period in my life and besides the missed period I have all the regular symptoms. I finally went for a blood test yesterday and now I'm waiting for results (should come Thursday or Friday). Half the time I feel 100% confident that I'm pregnant but the other half of the time I'm worried that I'm crazy or something. What gives? Anybody else have to get a blood test to finally get a BFP?? Are my odds good?? HELP! Thanks and baby dust!
