Ay, maternity benefit stuff talaga ang pinaka-confusing, kapit lang! Based on what you're saying, ang PRN usually generates once the contribution is actually due, so if September's due date hasn't arrived yet, that's probably why walang PRN pa, not a system glitch, just timing lang. The best move is to ask your employer directly kung kelan exactly ma-generate ang September PRN once the due date comes, kasi once na-generate na niya at nabayaran on time (or kahit slightly after ang payment processing), it should still count as part of your qualifying period for the maternity benefit computation. Hindi automatic na "late" kung ang PRN mismo ay hinabol lang nila, SSS looks at the contribution record, not necessarily kung gano ka-fast nila na-process. Since may specific rules ang maternity benefits with qualifying periods, I'd really suggest contacting SSS directly or your employer's HR to confirm kung paano exactly ma-count ang September contribution once paid, basta magpakita ka ng good faith na sinusubukan ninyong ma-settle on time, wag mo na pagsisihan after! Good luck, momshie!
