Recent miscarriage...*update*

almost a month ago on 4/14/18 i had a miscarriage at 6 weeks 5 days. im still bleeding since then. i slowed down to light spotting a week ago but 3 days ago i started bleeding heavily again. i had my blood drawn 2 weeks ago and my HCG levels were only 310 so it should be 0 by now right? when will i stop bleeding? when will i get my period again? am i on it now? I dont have cramps like i do every period of my life. whats going on?????? 😰😰😰

*UPDATE*

My doctor just called and said my HCG levels are at 24 as of 5/9/18
