Bleeding for more than 2 weeks after miscarriage

So I posted earlier how this came about, how I missed my period and had an early negative preg test result, weeks after I started seeing blood.

Well I went to the ER, they did all they could to make sure they found out what was wrong, if do blood work which showed I was preggy but the scans showed nothing was in there.

A week after managing the pain and leaving the hospital I AM STILL BLEEDING!??!

I am confused and don’t know if it really takes this long for a miscarriage to flush out? It saddens me that I’m not pregnant and still going thorough this.

Ps: Please does anyone relate or have any solution to what’s happening to me ?
