Miscarriage. Line not disappearing

Ashley

Found out I was pregnant 7/12/21. About 3 days late. Went to the ER because I started bleeding 7/21/21. Told me it was a possible miscarriage. The next day passed a clot and the day after that passed another. The spotting started 7/16. It is not 7/26 and the bleeding is pretty much gone just light spotting. But lines not going away. Seem a tad darker. When are they supposed to go away? Help please
