Is a woman sinful if her fetus dies in the third month?

Question:
This questioner says: A woman delivered a dead fetus in its third month, and the cause of its death was like that of other fetuses that die in their mothers' wombs, except that the woman believes, to a degree of less than one percent, that she is the cause, and that is through the position of intercourse, which may have been the cause, given that the husband had warned her about it?

Answer:
In the third month, there is no life and no death. The fetus does not become alive unless it completes four months. If it completes four months, the soul is breathed into it, and it becomes alive. As for before four months, the miscarriage has no life in it; it is dead from the start. Yes, and there is nothing required of her, nor any expiation.
