Well, the aldara website says that people have noticed changes within a few weeks to14 weeks, so I guess it's maybe possible? But I don't know, that still does sound kind of fast.
All I can personally suggest is to watch and see if more "warts" show up, as well as take vitamin supplements and exercise to keep that healthy immune system of your active.
I hope someone can come spread some more insight for you.
Good luck! :)
