SSS MATERNITY BENEFITS

Hi mommies! I got an email na from SSS about my maternity and upon checking their website nakita ko yung eligibility ko and kung magkano makukuha ko. Sabi ng employer ko makukuha ko to bago yung due date ko. Pero walang nakalagay na exact date kung kailan makukuha, kailan kaya ito papasok sa bank account ko?
