Faint positive for a week??

Hi everyone!

I think I’ve tested positive for a week now..I test every morning and it’s extremely faint. See picture below…what do you think?

If this test is positive then I’d be about 4-5 weeks pregnant…period is a week late. I was hoping the lines would get darker each day but it’s not :( anyone experience this before and have a healthy pregnancy? My fear is something is wrong. I haven’t had any bleeding or spotting. With my first baby girl, I got a strong bold positive very early on.
