Krisos 6:4

Let’s say that a person had to bring a sin offering or a definite guilt offering but Yom Kippur arrived. In such a case, one must still bring the offering after Yom Kippur. One who must bring a conditional guilt offering, however, is exempt. If a person doubtfully commits a sin on Yom Kippur, even as it’s starting to get dark, he is exempt because the entire day effects atonement.

Krisos 6:5

If a woman must bring a sin offering of a bird because of a doubtful miscarriage but Yom Kippur arrived, she must bring the offering after Yom Kippur because it is necessary to enable her to eat from sacrifices. When it comes to a bird sin offering brought because of a doubt, if the doubt is clarified after the bird’s head has been nipped, then the bird must be buried.
