Super worried... any thoughts?

I feel like my tests should be darker and its driving me insane with fear of miscarriage. 😭😭😭

Here is the first test on July 4th around 4pm

Barely there but it's positive right?!

Okay so here is one from July 7th around 9am

It's only a tad darker, but still it's darker right?!

Okay now here is the 9th around 6 am

Only a tad bit darker right?! So now I'm thinking I'll try a different brand

Here is a different brand on the same day (9th) 10pm

It's a clear positive to me at this point, but it's not as dark as I feel it should be.

Here is this morning (July 11th) around 6 am

I can clearly see the line is progressing but I'm supposed to be 5+4 apparently based on lmp, and I don't think my hpt's support a pregnancy in the fifth week. My lines should be the same color darkness by now.

Anyway I've decided to quit testing but only because I feel defeated, and I'm pretty sure I know the outcome of this situation.

Can anyone shed some light on my daunting situation, I'm super confused and really down right now 🙏😢😔☹
