Period or abnormal bleeding

Hi all,

So I had a miscarriage in November and had to have a d & c and ever since been a bit off. I got my first normal period in December and than January normal but had spotting couple days after my period and now I’ve been bleeding since day 16 and I’m now on day 21. I’ve very concerned. Like has anyone had a d &c; experience abnormal bleeding/period how long did it take to regulate? Like I had clotting for 3 days and now I’ve been bleeding non stop and it’s not ending... called the dr and feel like she doesn’t care and I just feel like somethings not right like maybe the procedure wasn’t correctly completed help!
