TTC after MC

Hi,

I've just had a miscarriage. Bleeding started 2days ago. Blood draw showed HCG drop to 73 yesterday. Yesterdays scan showed no sign of pregnancy - body has naturally passed everything. I'm still bleeding moderately.

I have SO many questions...

How soon can I expect my body to 'go back to normal'?

Does the MC bleeding work as like a period in terms of cycle days? So for example could I count first day of bleeding as CD1? or does my cycle start once my HCG is back to 0?

Is it safe to start TTC right away?

How soon after MC can I ovulate?

If you've had a MC, how long did it take you to fall pregnant again?

any other tips/advice?
