May I add that if the plant is fairly new to you, as it sounds, it may be having a little bit of transplant shock from being re-potted as well as reacting to a totally new environment in your home. It probably grew to this size in a greenhouse, so adding some humidity will surely help.
Good advice from both Karen and tarev on this. Give it a few months, and don't panic - those are pretty good, tough plants and aren't all that easy to kill. Do keep an eye out for insect pests, checking with a magnifying glass in the leaf axils (where the leaf meets the stem) and undersides of leaves once in a while to be sure . That's one thing that can get out of control somewhat, if you're not looking for it.
Keep us posted.
