11dpo and still a big fat negative result ! Any chances I could still be pregnant ?

I have seen on tons of forums people saying they could their BFP 7dpo, 8dpo and 9dpo. I’m 11 dpo and tested on 10dpo and today and a big fat negative. There isn’t even a faint line and my period is due in 3 days. Is there a chance I could be pregnant ?
