missed miscarriage?

I was told our baby was no longer viable (HCG dropped) at 5w3d, last Tuesday. 💔Follow up bloodwork confirmed it has continued to drop. Yesterday, my HCG was at a 2. I haven't had any progesterone in a week. I'm still not even spotting. When will my bleed begin? My doctor refused to give me the pill to start it or a D&C, as it was such an early loss. 😣
