Do you mean that the room is completely finished and arranged now? In other words, you finished the whole room despite now suspecting that the wall you opened up is load-bearing?
To begin with, I would promptly check using drawings whether the wall is load-bearing or not. If it is load-bearing, then more information is needed for someone with engineering knowledge to calculate it. What is on the upper floor, wall materials, etc. A sketch or even better, a drawing would certainly help someone with knowledge to give you an answer in the right direction.
