Hi! This sounds problematic. That's outside the normal max bleeding of 7 days. Anemia becomes a concern at this point. I would call your doctor and report that this is happening. While abnormality can happen after IUD removal, this is a bit much and a doctor needs to guide you. Is the pill something you'd consider?
The reason I mentioned the pill is that sometimes it is given to regulate cycles.
A lot of people have this issue upon insertion or removal of IUD. Dr. that remove the IUD, should have given you a list of warning signs to look for afterwards.
