Periods after a miscarriage

How long does it take for your cycle to return to normal after a miscarrige? I miscarried at 5-6 weeks on the 4th march. I had a blood test that day that showed my hcg levels we're pretty much back to normal. So i'm just wondering when to expect my period? I use to have regular 28-30 day cycles and its been 33 days since i miscarried.
