Is what the questioner understood from the previous fatwa correct, which is that she should perform ablution and pray at the beginning of the prayer time, even if gas continues to be expelled, because she is not afflicted with سلس (incontinence), and that she should pray by gesturing for prostration because gas is often expelled from her during it?

One must beware of giving in to waswas (obsessive whispers), as it leads to great evil. If the time when the impurity ceases is unknown, then your ruling is that of one afflicted by sals (incontinence), and it is incorrect to say that you are not. If the sals affects you during bowing (ruku') and prostration (sujud) but not during gesturing (ima'), then the obligation is to perform ruku' and sujud even if the sals affects you. There is no harm in emulating trustworthy scholars and adopting any of their opinions.
