:hugs: to you - it sounds like such an emotional day for you. I hope the blood results come back quickly. Please seek comfort in that HPT's give false negatives much more frequently than false positives. The test that you did in the docs surgery this last time could have been from a bad batch, it could have been a weaker urine sample... there are lots of reasons for it coming up with the negative result.
As Caro said, there is a brand of HPT's that tells you in words if you are pregnant or not - you can always give them a go if you are seeking more comfort. I used them when TTC and never had any drama's with them.
I'm sending you loads of and positive thoughts. Make sure you come back and let us know when the blood test results are in.
