Just a little bit of info for you.

I used to work in a lab before I became a Mummy and a negative HCG BT is <5, results that are between 5 and 25 are usually reported as inconclusive or indeterminant, results >25 are considered positive. Most labs do not actually do the qualitative HCG tests anymore as they are done on an automated analyser and you get a number regardless of wether the Dr asks for a qual HCG or quant HCG meaning that all results are actually quantitative. As your bt result was what the Dr called inconclusive it actually means that your BT come up with a result less than 25 but more than 5 and that your not, not pregnant but the result isn't high enough to be called pregnant either. The presence of HCG in your blood means there is something going on so routinely these inconclusive results are sent to the Dr with a comment asking for a repeat BT in 7 days to check that the level is rising as it should be if you are pregnant.

I hope that's not too confusing.

I've got my fingers crossed that you get a nice large number and you can relax and enjoy the ride!
