Still have a chance?

Jennifer • Finally expecting after being diagnosed with unexplained infertility. Pregnant with #1,happily taken by my amazing boyfriend! ♥️08-06-22🤰
I'm 10 dpo and I took a digital pregnancy test with weeks estimator and it said not pregnant and a few days ago I thought I saw a vvfl on a clear blue test but I was told that it was negative by the person I showed it to, my period isn't for another week, is there still a chance I could be pregnant ? 
My husband and I have been trying for 9 months with no luck and we were really hoping this was our month
