Oo naman, mommy! Marami sa amin dito nag-iinom ng calamansi juice, it's safe and super refreshing, lalo na pag mainit! A few of my mum friends swear by it kahit pregnant or breastfeeding pa lang kami, pero balance lang with water kasi acidic talaga and some say it can affect milk supply if sobra-sobra, so moderate lang. Kung worried ka, better ask your OB just to be sure, pero sa karamihan ng amin it's totally fine at nag-eenjoy lang talaga kami ng fresh calamansi drinks!
