I was 5 weeks when I miscarried. Do you pass the sac?

Its been about a week since they seen a mishapen embryo and sac on the ultrasound. I was bleeding like a period and passed tissue but during my last mc I passed the sac. I'm just spotting light brown now. Is it possible that the sac absorbed into my body? The doc wanted to do a dnc but I said to wait a week and he agreed. My levels were going down but I'm waiting for yesterday's numbers.
