Implantation bleeding 7dpo- bfn 10 dpo


Hi everyone, I’m ttc my first child and I’m in my 5th cycle of trying. I had some light spotting on Sunday morning, which would have been 7dpo and what I was hoping was implantation bleeding. I tested today (10dpo) and got a bfn. I used an early detect test so I was really hoping to see at least a very faint line. Is it still too early? I had so much hope this round but am starting to prepare myself for another disappointment. Looking for any thoughts or advice. Thanks!
