SSS Maternity Benefits

Kung kakaresign lang po from work and nagself employed do i have to change my status to self employed? Pero no need na naman daw po maghulog since macocover na nya ang january which is my due date. Ang concern ko po baka di ko makuha benefit kung di ako magiiswitch? O mismong employer na po nagpprocess nun once na nagresign ka sa kanila?
