Are there any supplications to ward off deformities from the fetus, and how can one overcome the whispers of Satan, especially after repeatedly committing a forbidden act concerning food cravings during pregnancy?

Among the general supplications that have been authentically transmitted is: "There is no deity except You; exalted are You. Indeed, I have been of the wrongdoers." No Muslim supplicated with it except that Allah responded to him. And frequent seeking of forgiveness; for whoever adheres to it, Allah will grant him relief from every worry, a way out from every difficulty, and provide for him from where he does not expect. And the Muslim should frequently seek refuge from Satan and recite Surat Al-Ikhlas and the two Mu'awwidhatayn.
