Need opinions please ladies!

Okay so, my AF is now 2 days late. 
​-took test a week ago& negative.
​-VERY sore boobs
​-nausea but no vomiting
​-no sign of AF at all 
​-stuffy nose/sore throat but don't really feel 'sick'
​I'm scared to test again!! Thoughts?!
​Has anyone gotten a BFP after a BFN a week before?
