Niddah 45a:9
A woman named Yostani, daughter of Asuerus ben Antoninus, came before Rabbi and reported that she married at six years old and gave birth at seven years old, contrasting with the Rabbi's statement that a woman typically marries at three years and one day and becomes pregnant at twelve years and one day.
תָּנוּ רַבָּנַן: מַעֲשֶׂה בְּיוֹסְטָנִי, בִּתּוֹ שֶׁל אַסְוִירוּס בֶּן אַנְטֹנִינוּס, שֶׁבָּאתָ לִפְנֵי רַבִּי. אָמְרָה לוֹ: רַבִּי, אִשָּׁה בְּכַמָּה נִיסֵּת? אָמַר לָהּ: בַּת שָׁלֹשׁ שָׁנִים וְיוֹם אֶחָד. וּבְכַמָּה מִתְעַבֶּרֶת? אָמַר לָהּ: בַּת שְׁתֵּים עֶשְׂרֵה שָׁנָה וְיוֹם אֶחָד. אָמְרָה לוֹ: אֲנִי נִשֵּׂאתִי בְּשֵׁשׁ, וְיָלַדְתִּי בְּשֶׁבַע. אוֹי לְשָׁלֹשׁ שָׁנִים שֶׁאִבַּדְתִּי בְּבֵית אַבָּא! וּמִי מִעַבְּרָה? וְהָתָנֵי רַב בִּיבִי קַמֵּיהּ דְּרַב נַחְמָן: שָׁלֹשׁ נָשִׁים מְשַׁמְּשׁוֹת בְּמוֹךְ — קְטַנָּה, מְעוּבֶּרֶת, וּמְנִיקָה.
§ The Sages taught in a baraita: There was an incident involving a gentile woman called Yusteni, the daughter of Asveirus, son of Antoninus, a Roman emperor, who came before Rabbi Yehuda HaNasi. She said to him: My teacher, at what age is a woman fit to marry, i.e., at what age is it appropriate for a woman to engage in intercourse, which would therefore be the appropriate time to marry? Rabbi Yehuda HaNasi said to her: She must be at least three years and one day old. Yusteni further inquired: And at what age is she fit to become pregnant? Rabbi Yehuda HaNasi said to her: When she is at least twelve years and one day old. She said to him: I married when I was six, and gave birth a year later, when I was seven. Woe for those three years, between the age of three, when I was fit for intercourse, and the age of six, when I married, as I wasted those years in my father’s house by not engaging in intercourse. The Gemara asks: And can a minor of that age become pregnant? But didn’t Rav Beivai teach a baraita before Rav Naḥman: Three women may engage in intercourse while using a contraceptive absorbent cloth, a soft fabric placed at the entrance to the womb to prevent conception, despite the fact that this practice generally is prohibited. They are a minor; a pregnant woman; and a nursing woman.
