Is this a normal line progression?

Al

Hey ladies!

This would be my first time pregnant. I decided to test early (9DPO) because au had a feeling I should. I still can’t believe I got my BFP. And, I am stressing that my line progression isn’t the greatest or that it can turn into a chemical … could someone please give me any input? Thank you in advance!
