Negative at 10 dpo, still hope?

Anyone on here got a negative result 10 days po with first response test, but gone on to get a positive in the end? I got a negative this morning 10 dpo (I know I know, I shouldn't have tested so early really, glow did warn me!) since now I'm so disappointed but also can't help feeling a tiny bit hopeful still- I just feel pregnant!   First response does seem pretty accurate 4 days before your period though so maybe I'm kidding myself (and my last pregnancy- which sadly ended on miscarriage- I got a positive at 11 dpo).  Any thoughts welcome, thank you!
