12dpo BFN.. Is there still hope?!?

Char • Mother to one beautiful Son😍
Am super bummed out and I have to get to work and carry on like am not dying inside. I took the first response 5 day early one and got a big fat negative. My AF is due on Friday or Sunday according to my other two apps (ovia and essential baby). Am hoping glow miscalculated my ovulation date and am actually 10dpo rather than 12. Has anyone experience this and still got a positive or is anyone in the same boat right now. Am soo sad I just started crying.
