Hello I'm Having A Problem With My Pregnancy Last Week

Hello I'm having a problem with my pregnancy last week my baby had a heart beat and you could see the baby I was 7 in a half weeks but sun I turned 8weeks but yesterday I was spotting brown stuff that really smells bad I went to the doctor and they couldn't see a baby or a heartbeat so I was told I was having a miscarriage by 1 doctor that's a female I go back today and the male doctor checks to see if I'm bleeding but I'm not I only spot the brown stank stuff so he does a sonogram and there's know baby insite or a heartbeat so they tell me to wait until next Thurs to get the operation done which is the DNC but I'm very scared to be walking around if I have something dead in me for that long that can really have me sick. So I'm trying to figure out what should I do because my doctor says the hospital is not doing operation this week so I have to wait til next week but I feel as if I have an emergency
