Bestie, suntik perancang biasanya bertahan 3 bulan, tapi ambil masa a few months untuk fertility mu balik normal after stopping, ada mum friends yang pregnant dalam 1-2 bulan, ada yang ambil sampai 6 bulan lebih, depends on your body je. Since your baby is 4 months old, it's best to check with your doctor first to make sure you're fully recovered and ready for another pregnancy, plus they can advise on timing yang best untuk your health!
