Scholars agree it is forbidden after the soul is breathed into the child (taught to be 120 days) unless the mother's life is in danger. Before that, they differ: some forbid it unless there is a real need, and others allow it for a valid reason before 40 days. The Quran forbids killing children (17:31, 6:151). Ask a scholar and a trusted doctor.
De ki: "Gelin size Rabbinizin haram kıldığı şeyleri söyleyeyim: O'na hiçbir şeyi ortak koşmayın, anaya babaya iyilik yapın, yoksulluk korkusuyla çocuklarınızı öldürmeyin, sizin ve onların rızkını veren Biziz, gizli ve açık kötülüklere yaklaşmayın, Allah'ın haram kıldığı cana haksız yere kıymayın. Allah bunları size düşünesiniz diye buyurmaktadır."
This is general information, not a fatwa. For your own situation, ask a qualified scholar.
