Talmud for Ketubot 43:12

One day, she said, I am married. The next day, she said, I am divorced. We asked her, yesterday you said this, today you say otherwise? She said to them, because of a group of amoral people who wanted to start up with me⁹⁹She needed the protection given in society to married women.. Rebbi Abun in the name of Rebbi Ila: Since she provided an explanation for her words, she can be believed¹⁰⁰In the Babli, 22a, the case and its resolution is tannaïtic, attributed to the Sages of the court at Usha (probably under Antoninus Pius).. A similar case: Samuel wanted to sleep with his wife, but she said to him, I am impure¹⁰¹And therefore forbidden for an additional 10 days.. The next day, she said, I am pure. He said to her, yesterday, you said impure, today pure? She said to him, I did not feel well enough at that moment. He came and asked Rav, who told him, since she provided an explanation for her words, she can be believed¹⁰²In the Babli, 22a/b, Samuel accepted the ruling for everybody except himself; cf. Tosaphot 22b, s.v. ואפילו..
