Couldn't help but post, I can really feel your anguish. Unfortunatly there is little that can be done to reassure your worries, other than what other ladies have suggested (private scans and keeping busy.) My advice, just believe in what you can't see or control, you have too. Early prg after loss is kind of like the Pacific Ocean, you know its there, and sometimes you can see/touch it, but mostly you can't, you just trust in what you believe. Just believe PZ, we do.
Much faith and love.
