They should have done an ultrasound today. You can also go to the ER and tell them you're bleeding and they can do one. If you've not already, make sure to take it easy. No lifting things, no sex (obviously), and keep hydrated.
i have been today had a positive pregnancy test and felt my stomach, wont be getting scanned until monday so a nervous wreck until then :(
Have you gone and gotten looked at? Any bleeding should be reported to your doctor immediately.
