Miscarriage

So I went in for a follow up appointment because last appointment my baby had a slow heart beat at 6 weeks so I went in today at 7 weeks and dr told me baby had no heart beat. Dr gave me 3 options one was by getting a d&c procedure but can have complications or he can give me the medication to start contracting and it will come out or 3rd is letting it come out on its own i choose 3rd option I’m like will I need to go to the hospital he’s like No unless you are bleeding way to much then yes go but no need to .he told me I would pass the sack and just have blood like a period but heavier . I’m scared anyone go through this
