disappearing then reappearing symptoms

Okay. I am so confused right now. I had sore breasts a few days before AF was due. Not sure exactly when I ovulated as my test device showed high for 5 days and I never got a peak. I had to stop testing because I ran out of strips. Damn flashing smiley face! ;) Anyway sore breasts went away and I expected AF right on time. I'm now 6 days late and 2 tests in but both BFN!! I had no symptoms of pregnancy or AF until my breasts became really sore again late last night and it's only become worse today. Still no sign of AF. Anyone else ever have the same issue? Any ideas? I'm totally stressing out right now with not knowing!!
