Faint test?

Hi! Sorry for all the posts today, I posted today about finding out I’m pregnant. This morning at 9am I took this test:

It was pretty noticeable! But I took it after a night shift (got home around 9am and took the test), so there wasn’t an all night hold or anything.

Went to bed, woke up around 4 pm and took this test:

It’s a lot lighter it seems like, not so noticeable. Is this ok? According to an app I have, I’m only 3 weeks 3 days 😳 I just don’t want what I see a lot on here to be a chemical pregnancy 😞 I also took a digital (I think it might’ve been invalid though before I even took the test but I took it anyway🤷‍♀️) and I know they take more hcg but it came back negative.
