Is expiation required from someone who caused the death of a fetus after phone calls led to the pregnant girl fainting and her mother being hospitalized?

You must repent from speaking with a foreign woman unless there is a need and it is done according to legitimate controls, because failure to adhere to this leads to serious corruptions. You must be careful not to return to such a relationship in the future, and be keen on marriage to preserve your religion and soul. If that is not possible, then fast and avoid everything that incites desire. There is no sin or guarantee upon the questioner for what happened to the girl, such as fainting, or for her mother, such as a miscarriage; there is no connection between his words and what happened to them.
