BFN, is there still hope? :(

Courtney • Married to the love of my life and trying to conceive our one baby to complete our small yet mighty happy family. ❤️
Today I am 10 DPO and I decided to test using a generic "5 days before missed period" blue dye test. I got a huge BFN, no faint line, nothing. 
​I'm really upset over it. My period is due in 4 days. Does anyone think there might still be hope? :(
