I agree that 'inconclusive' sounds like it may be too soon to be a yes, coz it sure doesn't sound like it's a no.

I reckon another BT in a week or so should determine the outcome one way or another, though I know the wait will be excrutiating! At 13dpo, my HCG was only 73, so at 10 dpo, I reckon it would have been under 25 as well, as it was tripling every 48 hours at that stage.

Good luck!
