I'm so sorry, I know this is a stressful time. I've had lots of issues in my pregnancies with bleeding. Some ended in good results and others poor. It's difficult to tell at this point. It sounds like you are doing everything correctly, so I would try not to worry.
If you are bleeding a lot, I would put myself on bed rest whenever I could, with feet up and lots of fluids until you go back to see your doctor.
Best of luck.
