Can you test with 2 hour old urine?

I wake up between 6-730 every morning having to pee. I wanted to take another test today to make sure the line is getting darker. The store doesn’t open til 8. I peed in a cup and I have it I the bathroom cabinet right now. I won’t be able to use it for another 90 minutes. Do you think it’s ok? Or would I be better off waiting until I have to pee next? I’ve read different things.

Update: I do have to pee again and haven’t had water so it should be just as good right?
