Should a girl tell her fiancé what happened to her in the past regarding the loss of her virginity, and what should she do to avoid scandal?

This tragedy is one of the consequences of forbidden relationships that lead to indecency and shame. Adultery has dire consequences in this world and the Hereafter. The punishment for its perpetrator is flogging or stoning, along with severe torment in the fire of Hell. The girl must repent sincerely and make abundant supplications for Allah to conceal her. She must also conceal herself and not inform anyone of her sin. If anyone becomes aware of what happened to her, they must conceal her, help her, and employ stratagems to obtain the recording made by the criminal.
