Is my lip filler migrated or is this normal?

No photos are present. I suggest either post photos and your question again, or go get a second opinion.

I can’t see included pictures, so it’s hard to make an assessment. At nine months any previous filler should be mostly gone. Some patients who’ve had multiple treatments with filler may have residual volume not related to residual product. We don’t know what this volume is caused by but most likely it’s scar tissue due to chronic inflammation from having multiple treatments.
Consider giving lip, fillers, arrest and getting back to baseline to have a clear assessment of what your lips look like without product.
Likewise, you may also want to consider your provider and if they are of sufficient caliber in regards to quality work. In my experience, fillers, do not migrate. This concept is overused as a poor excuse for poor technique.
