What is the ruling on prayer and fasting when a sticky white discharge occurs a day or two before menstruation, or a week after menstruation, and is it necessary to repeat ablution for minor or major impurity?

The viscous white substance falls under the ruling of discharges (secretions). If it is continuous, it takes the ruling of urinary incontinence ( سلس البول ), requiring ablution (wudu') for each prayer after its time has begun, and its subsequent emission does not cause harm. If it is not continuous, the majority of scholars hold that it invalidates ablution, and it is more cautious to act upon this. These discharges are pure (tahir) according to the more preponderant opinion, so washing clothes from them is not necessary, and they have no effect on fasting.
