Sayang, sorry to hear about what you're going through, take your time to heal physically and emotionally. For something specific like berapa hari boleh ambil vaksin after a miscarriage, kena check with your gynae or doctor directly sebab each situation lain-lain, and they'll know your medical history best. Most of us kena tunggu sampai fully recovered and cleared by doctor dulu before any vaccinations, tapi timing tu betul-betul depend on individual circumstances and jenis vaksin jugak.
