Is this normal for 8dpo?

I got a faint line yesterday on the wondfo and easy@home tests. They’re a little darker today not by much. But I took a frer and it was coming up before the control line. In my last 3 pregnancies (2 to term and 1 loss) none of them were positive at 7dpo. This one at 8dpo is twice as dark as my first and healthiest pregnancy which I found out at 13dpo , and my third when I found out after my missed period. Is it concerning that it’s this bold this early?? Also I saw a faint line that I could get on photo on 6dpo!
