Is it permissible to abort a fetus if the mother is struggling with raising her young children and with the pregnancy, especially with the possibility of uterine fatigue?

Abortion is forbidden in the third week unless there is a confirmed harm to the mother's life or the fetus's death. What is mentioned in the question is not a legitimate reason for abortion. One must fear Allah, supplicate, seek well-being, and follow up with doctors for a safe completion of the pregnancy. It is permissible to regulate pregnancy after childbirth for breastfeeding and the benefit of the child and mother.
