Drains smell on butt implants? I should be getting my drains out tomorrow I've had them for 2 weeks.

For about 5 days I've had dark red drainage without odor I called my ps and the nurse told me it's probably old blood. But about 2 days ago it started smelling bad or strong but the drainage has also Deminshed. On one side I'm draning about 10 cc per 24hours and in the other about 15cc . Is it normal for it to smell because the drainage is stopping or because maybe it's old blood? I haven't had a fever and I don't see redness
