Scared to test AGAIN.

Ladies,
I know I'm the typical, Am I pregnant post, but I really just need insight- I am too nervous to test, but I do need to get blood work done on CD35 if AF doesn't show.
Could I have tested to early and HCG not come up or could I be too hydrated for HCG to show on a at home test? I seriously only drink water, nothing else, and my last test was done mid-afternoon. I don't want to over read my body right now, but BBT is high, cervix is high/tilted, and have creamy white CM
Any insight?
