Home pregnancy tests are wildly unreliable for testing your hCG levels. They aren't recommended for using for progression because there are dozens of reasons for the level of hCG to vary in your urine or for the test to be lighter. Plus, all tests have a max point where they stop working and could potentially even start getting lighter due to a thing called the Hook Effect.
That being said, I know what you are feeling. I've been battling recurrent pregnancy loss issues for over a decade now and I'm at the point where the whole first tri is nothing but a 3 month long panic attack.
When you've experienced loss, it's hard to trust that things can and will go right. And it's the not knowing what is going to happen that is the hardest thing to bear. If you knew which way it was going to go, it would be better because you would know.
But you don't know and in most cases, you can't know, especially this early on. And that's really really hard.
My best advice is to do what you can to relax. Hard, I know. But do your best.
Find a mantra-I usually tell myself something like 'Today I am pregnant. I don't know what tomorrow or tonight or even the next minute will bring but right now, in this moment, I AM PREGNANT. And it's enough.'
Pamper yourself with an at-home spa day.
Make a shopping date with your bestie.
Go on a date night with your OH.
Do some pregnancy yoga.
Read a book.
Do whatever you can to at least try and distract yourself a bit.
And lastly, step away from the pee sticks. They can't tell you anything and honestly, they just add to your worries. At 5 weeks, your hCG levels are likely pretty high and after a point, the test just doesn't work right anymore. And really, you just have to trust that things are okay. (I know, I know. Easier said than done.) But it's the honest to goodness truth.
So take a deep breath, put away your remaining hpts, and just do your best to shove the fears and worries and concerns into a mental box that you can then bury in your mental closet of Things You Don't Need.
