Next period after early miscarriage

I’m currently on day five of my heavy bleeding from my early miscarriage (5 weeks) my hcg never got really high. The first time I had it checked it was 72. Then two days later 11. And currently waiting on results from yesterday. Question is how long until I can expect my period to come back. Especially since I should have almost or all hcg gone now. Really hoping my period returns to normal because I had irregular periods that became regular after I gave birth to my son. Really hope they don’t become irregular again. My pregnancy tests are coming up negative now as well
