Oo naman, calcium at iron dapat continue mo talaga hanggang end ng pregnancy kasi kailangan mo pa for baby's bones at para hindi ka maging anemic! One of my mum friends actually nag-stop ng iron early and natinding-tig siya sa third trimester, so kahit feel mo okay na, better safe than sorry talaga, pero best to confirm din with your OB kung okay pa ba dosage mo or kung kailangan adjust, lalo na if may side effects ka.
