Line Progression Question!!

R

So I had a very very faint positive on 10 DPO. For anyone who has also tested this early how long did it take for you to really see a line progression??

I know it can take a couple days for hcg to start to increase but as someone who has experienced loss previously I’m just extra anxious when I see the line still faint and not getting darker.

Any input is appreciated ❤️❤️❤️
