8dp5dt neg hpt

Michelle🐶 • 8 angel babies, now divorced but still hopeful for my first human child - already have my pitbull fur baby!!
Hi all,
    I'm wondering if any one knows/had experience. I'm going for my beta tomorrow but caved and have been taking hpts. They've all been negative. I used first morning urine, but it's always diluted. (I drink a lot and pee at least 2x/at night). My most recent - this morning - super negative. I desperately searched for the smallest, faintest, line but nothing. Is 8dp5dt really too early, or am I just holding onto hope for no reason?
