Ay nako, condolences sa iyo, mama. The SSS maternity benefit process for miscarriage can take a few weeks to a couple of months kaya kailangan mo ng patience, pero honestly depende rin sa kung complete na lahat ng requirements mo at kung responsive ang SSS office sa area mo. I'd suggest you go in person to your nearest SSS office with your complete documents (medical certificate, maternity notification form, etc.) kasi faster ang processing pag nasa office ka na mismo instead of online lang, a few of us tried both and ang in-person approach talaga mas mabilis. Condolences again, and remember to take care of yourself emotionally din during this time, ha.
