2WW Dread

Well it is 8dp3dt (8 days passed 3 day transfer) today and I tested yet another BFN this morning.  I'm starting to worry that our two little embabies didn't hang on.  I've been using wondfo internet cheapy tests which make me go cross eyed to look at and have me imagining lines on everything now.  I only have 2 first response tests so I plan to use one tomorrow.  I'm so hoping that it was just the cheap tests that was the problem but now I'm worried that if I get a negative again tomorrow it'll be the real deal.  I want this so bad and this two week wait has been the worst!  Please oh please oh please let there be a second line tomorrow!  Beta is scheduled for Friday morning.
