Never-ending miscarriage?

Jen • I'm 34 with b/g twins via IVF FET, born 11/2016. Had a mc after first IVF/FET, 3 failed IUI, mild endo. 1% morphology
It's been a month and a couple days since my D&C for a missed miscarriage. I haven't stopped bleeding yet (and I was bleeding for a couple weeks before that). Is anyone else experiencing this? I'm told the D&C might not have gotten everything out. Really hoping my body passes the rest soon!
