Change Civil status bago magclaim ng Mat2

Hi mommies question lang, employed po ako and nung nagnotify ako sa sss (mat1) about my pregnancy naka-single pa po ako sa record.. I'm about to change it na po to married now kaso I've heard from some mommies na nagkakaissue silang magclaim ng mat2. Is it better po na magchange status nalang after kong ma-claim yung mat2? Thank you in advance
