What IS going on down there??

I am either 4 days late, or 3 days before af [I had a wacky cycle] and all hpt's have been BFN :[ But this morning I woke up with a very persisten tingly sensation in my vagina! More around my clitoris, I think. Did anyone have this and get a BFP? I'm scheduled for a blood test October 8th if af doesn't come. If I skip, it will have been 60 days since my last period.
Also tired, frequent urination, and swollen [but not sore] breasts.
