laila sees herself as sacrificing her virtue for her child. Explain?

Laila had once thought about leaving Afghanistan before she had heard the news about Tariq's death. Soon after, she realizes that she is pregnant and now cannot leave. Laila considers the unborn child to be a miracle - a memory of Tariq. Marrying Rasheed is Laila's method of providing for her child. If they are married soon enough, Rasheed will be deceived into thinking that the baby is his. Laila and Rasheed marry and consummate their marriage, but Laila has to prick her finger in order to feign the loss of her virginity.
