The first questions to answer here would be, if you actually suffer from a supression in rankings based on your link profile.
This could be signaled by certain keywords, pages or folders ranking a lot worse than they did before.
An algorithmic supression doesn't happen sharply, and a recovery will not be visible as a sharp jump either. Google's systems are reacting slower here to make a reverse engineering harder than it used to be pre-2016.
Very often after a pro-active disavow it's unclear for a long time, if a supression was lifted or not. Often there are many other marketing activities going on, that have an impact on the rankings, or even the search volume (think about PR here).
