Faded lines?

Me

Hi all.

Got my positive Saturday- 2 of the stick tests -2 lines (a little faint) then a digital test to confirm. Re-tested yesterday and still got 2 lines (still a little faint) re tested this morning and I feel like the 2 lines are fainter? As first time pregnancy I’m worried about EVERYTHING. Trying to get in my gp ASAP this week but can anyone reassure me? There’s definitely still 2 lines they are just still faint and I expected them to get darker?!? Don’t want to be a stresser about everything and want to try and enjoy it.
