Must one repeat ablution and prayer upon feeling a moving wind or smelling an odor, especially if this occurs frequently during and before ablution?

The situation of this woman revolves around two possibilities: Either she is afflicted with continuous flatulence (incontinence of wind). If it does not stop for a period long enough for purification and prayer, then she must perform ablution for each prayer after its time has begun and pray, and what exits from her during the prayer will not harm her. However, if it does stop for a period long enough for purification and prayer, then she must wait for the time of its cessation. The second possibility is that she is afflicted with obsessive whispers (waswasah). In this case, she must completely ignore them and should not perform ablution unless she is certain with absolute certainty that her ablution has been invalidated.
