Hi There, Hopefully this will bump you back to the top so others can chime in. I really am not an expert, but I would say that it's better to repot and take the chance of losing the blooms and saving the plant. If you do it very carefully, it may be okay and not miss a beat in the blooming process, but no garantees.
What type of orchid is it? Some are more fragile than others when it comes to disturbing them. Still I would definitely repot. I would first take several pictures of it, and notify the company you bought it from. They should send you another orchid.
