To answer your question specifically, clipping IS an option. It is better to avoid it if you can. Ideally find good ways to manage the flying and crashing - ideas already given here; along with, work on target training and taming, etc. Certainly Better If Safe, to not clip.
I think your bird should naturally be learning soon to not hit walls and ceilings, and thus Probably does Not need clipped. (Btw, how small is the room? Could that be any part of this problem?) Also curtains over windows can help with window-crashing, if she is not yet tame enough to do the window-tour.
However. IF with some work you are not able to train/manage the Crashing... a Clipped Bird is Better than a Badly-Injured bird. IF you get her clipped, you want a very minimal clip. Your bird needs to be able to glide to the ground withOut crashing. (That is the whole point - IF IF you clip - to give her time to learn to Stop Crashing.)
....mmm I don't know the correct terminology for that type of clip, the right words for which feathers. You can search it on this forum or else someone else may chime in with the name/correct description of it...
Again, work on taming her, covering windows, target training etc, and that is Probably all you need. But, if she Continues Crashing, then, a wing clip could indeed be the safest choice. AS LONG as it is an even clip, of the type that leaves her fully able to glide safely to the ground.
