I wonder what would have happened had OP not mentioned the TOP at all, just the bleeding.
I suspect she would have been checked for anything urgent (ectopic pregnancy, signs of sepsis, or signs of impending shock), and then either reassured her pregnancy is ok just now, but still may or may not miscarry, if she was continuing, or asked to book in with the TOP service if she wasn't.
So actually, pretty much the same care.
OP, I'm probably being thick, but I can't work out why you'd necessarily be at a higher risk than any other woman having a threatened miscarriage?
I can't see how your treatment is different to any other woman having a threatened miscarriage? TOPs are done by the TOP service, and you can be seen by them tomorrow. If you're not in shock, and you're not septic, why demand it now?
Is this about doctors not being willing, or you being in an emergency bed, and an failed TOP is not an emergency? If the bleeding's settled, and your obs are ok, I get why they may not be worried about you waiting until you can go back to the service which treated you originally.
Are you ill? Or pregnant when you don't want to be?
I realise this is an emotive topic, but I'm fairly confident that in the UK, if you were haemorrhaging acutely, or septic, you'd get a STOP immediately, there will be someone on call. I suspect you're quite stable?
