Is it permissible for a woman to abort her fetus in its seventh month if the pregnancy is not from her husband and her marital life has become a living hell due to her husband's doubt about the lineage of the fetus?

Adultery is a heinous crime, one of the greatest sins after polytheism (shirk) and murder. The adulteress must hasten to repent to Allah, increase in righteous deeds, conceal herself, and not inform anyone of her crime.

It is forbidden to abort the fetus after the soul has been breathed into it, because it is the killing of a soul, unless there is a confirmed fear for the mother's life. The lineage of the fetus is attributed to the husband.
