If, during prayer, I doubt whether the wind exited from the anus or the penis, must I complete the prayer or exit to perform ablution again?

If a woman is certain that gas has been emitted during prayer, but does not know whether it came from the front or the back, she must stop the prayer, perform ablution again, and repeat the prayer. However, if it is merely a doubt, she should disregard it, complete her prayer, and does not need to repeat it.
