how long did it take to pass it after your mc diagnosis?

I was told Tuesday it looked like an early miscarriage, only a sac measuring at 5 weeks was in the US when I was 8 weeks along, Yesterday my doc called to confirm it is a miscarriage and Monday will meet to see if I had passed it and if not, I'll go to surgery right after. I have mixed feelings. I feel sad then angry then ok. I just want it out of me so I can keep trying again
