Is it possible for a girl to be pregnant after her fiancé ejaculated between her thighs with a sensation of the vagina being touched, even though the urine test was negative and her period is ten days late?

The questioner must repent to Allah Almighty for her sin, as a suitor is a stranger to his fiancée until the legitimate marriage contract is concluded. Repentance involves regretting the action, resolving not to return to it, and severing the forbidden relationship.

Allah forgives the sins of those who repent, believe, and do good deeds, as stated in His Glorious Words: "But indeed, I am the All-Forgiving to him who repents, believes, and does righteous deeds, and then is guided" and "Say, 'O My servants who have transgressed against themselves [by sinning], do not despair of the mercy of Allah. Indeed, Allah forgives all sins. Indeed, it is He who is the Forgiving, the Merciful.'"

Islamic law urges self-concealment and not informing anyone about what has happened, and to immediately sever the relationship with the suitor until the marriage contract is solemnized.
