Miscarriage 6 weeks

Im so confused whats happening with my body as this was my first pregnancy/miscarriage. I found out last week my hcg is dropping so stopped progesterone. Its now a week later and I have not started bleeding. Just spotting which was dark brown and now today red. Im feeling some cramps today so hopefully it will pass naturally and I start bleeding. My doctor is just checking my hcg levels once a week. Im worried if my body doesnt pass it naturally i will need a d&c or shouldnt my doc give me the pill to get the miscarriage going? She hasn’t mentioned anything about that yet.

Also is the bleeding that will start during miscarriage considered your period/cycle? And then when does your next period come after this miscarriage bleeding. And how long can i expect to bleed for? Since im pretty early at 6 weeks right now.
