HCG testing or let it go?

I took at HCG tests at 4 weeks and was at 116. My doc (not OB, just primary care) told me she doesn't think I should test again because I don't have any troubling symptoms, not high risk, etc.  I know that a good sign is that number doubling, should I ask to do another test or relax and just try to stop worrying and enjoy this??
