AF didn’t show but still a BFN?

AF was due today, no sign of her ugly face showing. I tested today (with the easy@home hcg test from amazon) when I woke up around 8 (I did go to the bathroom once in the middle of the night around 3 am) and still got a BFN. According to Glow, I’m 14 dpo.... I know I’m not technically out until AF shows but is it possible to still get a BFN even at 14 dpo if I could be pregnant?

I had a couple days of what could have possibly been implantation bleeding but I wasn’t sure considering I’ve never been pregnant before.

Husband and I just want to be parents so bad. We’re so ready and so over the waiting.

Thanks in advance:)
