Advice on HCG blood tests

Hey ladies,

I had an HCG blood test done when I first got my positive pregnancy test last Monday. I had some extremely light pink spotting between tests (but it has since stopped). They did a second test Wednesday and my levels were still doubling as they should, despite the light spotting I had (which has since stopped). Would you bother doing another HCG blood test, or just trust that all is well and stop worrying since I’ve had no other issues and my first round of tests were good?
