Oo pwede mo mismo i-file, mama! A few of us tried doing it ourselves sa SSS branch kasi din ang employers namin ay delay, and honestly mas mabilis lang pag ikaw na ang kumilos, bring your maternity notification form, ID, and marriage certificate (kung may asawa ka) and they'll process it mismo. Pero better din i-follow up mo talaga sa HR mo regularly kasi sila ang dapat mag-submit, pero at least alam mo na may backup plan ka kung patuloy silang tumitigil!
