Is it possible I didn't miscarry?

My levels dropped from 1400 to 300 in 48 hours. Doctors called and said I miscarried. Bleeding lasted a week and starting to slow now. I want to go out for a drink after this stressful week but don't see my doctor for an ultrasound until next week. I know I'm being crazy, but I just won't believe it till I see it. Anyone have this happen and didn't miscarry or am I safe to have a drink? 7 weeks along. Don't know how long baby was viable.
