Hi momshie! Hindi ako sure kung pwede yung dagdag sa na-advance mo na from Jan to March 2022 kasi ang SSS rules nila are super specific about contribution periods, but honestly the best move is to call SSS directly or mag-visit sa kanilang office, sila lang ang makakapag-confirm ng exact process para sa situation mo na yan, at baka may options pa na hindi mo alam! One of my mum friends had a similar concern with her contributions at nakuha niya agad ang sagot when she talked to them personally.
