Mishnayos Sotah Perek 3 Mishnah 6

If the meal-offering of the sota is rendered impure before it has been sanctified in the service vessel, its status is like that of all the other meal-offerings that are rendered impure before being sanctified in a service vessel, and it is redeemed. But if it is rendered impure after it has been sanctified in the service vessel, its status is like that of all the other meal-offerings that are rendered impure after being sanctified in a service vessel, and it is burned. And these are the sota women whose meal-offerings are burned if they have already been sanctified in a service vessel: A woman who confesses and says: I am defiled, and therefore prohibited to you; and a woman with regard to whom witnesses came and testified that she is defiled; and a woman who says: I will not drink the bitter water of a sota, even if she does not confess her guilt; and a woman whose husband changed his mind and does not want to force her to drink; and a woman whose husband engaged in sexual intercourse with her on the way to the Temple.
