MC and first period after?

I had a MC 4 weeks ago at 11weeks though they beleive I lost bub at 7weeks and just held on. My hcg levels returned to normal about a week later (I had an emergency d&c) and im sure I ovulated about a week and a half ago and I would be "due" af today but it was a no show and I got a neg test. Being my first MC I dont know when to expect af or really what to expect about now...
