Testing with the same wee?

So my question is if I use the same wee with five different tests will the hcg in the wee go out with each test? I did two cheap tests and faint positive done a clear blue digital says not pregnant but I no they are a highter miu another cheap and it’s negative ?? my question is if I go and buy a frer will there be enough hcg in the wee left to give another faint positive ?
