I passed a clear intact sac with what appeared to be a 6 mm embryo inside?

I need help. Sunday I went to the toilet. When I looked in the bowl, I saw a clear intact sac with a red 6mm tiny outline of a body. Now, I have had no pain, no bleeding, nothing abnormal. My breasts feel less tender and morning sickness has ceased. Did I miscarry? I can't find answers anywhere and my Friday dr appointment seems like forever away.
