4under3, when something so stressful is happening in your pregnancy you need sympathy and support not *****y nurses.
It must be awful having to wait another 6 days - maybe if you went to a GP and had a talk about the kind of emotional stress you're feeling at the moment they might refer you for an ultra-sound for peace of mind. If your nurse is always a ***** maybe you could ask to be assigned to a differant one. You could just ring up the clinic/hospital and ask what the procedure is to change your nurse or Dr.
I hope your bleeding clears up soon so that you can relax.
