How soon after early MC did you have your period?

Rachel
Hi ladies. This is my second miscarriage but different in regards to my Hcg levels. I miscarried in February at 9-10 weeks, miscarried, my levels were 8,500 then it took 5 weeks for my levels to reach zero and my period started. 
This time i miscarried on 8/19 and am still bleeding but my levels are at 301. A lot smaller than last time so I am assuming it won't take as long to reach zero. 
So as anyone only taken a couple weeks after miscarriage to start their period or how long did it take? I hope this makes sense. Just not sure if my body can shed lining again in only a couple weeks. Thanks!
