when to take a digital??

Destynee • PCOS • 2 natural born • pregnant with our letrozole baby🤍
I'm 10 dpo and got a BFP on a line test today! I've taken 2 other line tests since receiving my positive (all today lol) and all are positive!! I took a digital and it was negative. So when can I take a digital so it will say "pregnant" and I can take pictures for the family?
