What is the ruling on ablution (wudu'), prayer (salat), and fasting (sawm) with abundant, continuous vaginal discharge that has a strong odor, resulting from pregnancy-related infections in the ninth month, and what is the correct method for ablution?

Those discharges are either pure if they are from the vagina, or impure if they are from the urinary tract. Both nullify ablution. Ablution must be renewed upon their emission, unless they are continuous, in which case the woman should wash the area, protect herself, and perform ablution for each prayer after its time has begun. Her fast is valid.
