(Fatwa: 48/48/B=01/1437)
Under the condition which you wrote it is not a valid reason to abort the pregnancy. If there is fear of life due to the childbirth or it is feared that she shall fall sick permanently then it is allowable to abort the pregnancy before 120 days, otherwise not.
Allah knows Best!
