Hey mama! I'd request it ASAP talaga, a few of us moms did it around 5-6 months na, para may buffer time in case may delay sa HR or processing. Since your EDD is July, I'd suggest request mo na ngayon if you haven't yet, kasi employers can take weeks to process and you don't want to stress yourself malapit na sa due date. Better to have it ready early para focus ka lang sa pagprepare ng sarili mo and baby!
