SSS Benefits

I resigned last Dec 29, 2019. I went to SSS today to file a maternity benefit, sabi nila yung pagpunta ko dun is just to notify them na pregnant ako but yung pagpafile ng matben is kapag nailabas na si baby, kasi daw iaattach yung birth cert ni baby. Tama po ba yung advise sakin? Thank you in advance!
