Ay, I'm not 100% sure on the exact matben requirements for natural miscarriage kasi it's different from normal maternity, I think you might need to check directly with SSS or their hotline para sa specifics, honestly. Kailangan mo probably ng medical certificate from your OB showing the miscarriage, pero best na tawagan mo sila directly para sigurado sa requirements at kung covered ka talaga since it's a bit of a gray area compared to normal delivery.
