Lost length after being implanted. Is this normal?

[Archetype]

Few weeks ago I had the malleable implant and since the operation I have noticed significant decrease in length compared to my pre-op stretched length. Is this reversible with time as you go through the healing stages? From what I can read online you don't lose much length, if at all, from having an implant and if you lose it is minimal with much of it coming back with time. Anyone with experience can chip in here as I am concerned that they undersized despite being told that I had no fibrosis with good rods placement.
