When to take a digital?

Holly

I got a line at 8dpo on a wondfo test strips, yesterday at 9dpo I took a frer and got one also. It was light but clearly visible. Is it too early to take a digital test if my first response test was not as dark as the control line?

I took another wonfo strip test this morning, And the line was either the same or a little bit darker than the one I took at 8dpo. I'm currently 10 dpo at least I think so. I'm 4 days away from my expected period Do you think I should wait until I miss my period to take a digital or do you think because I got a positive on 8 dpo, I might get a positive on it today?
