Mommy, congrats sa November baby! Para sa ganitong specific na tanong tungkol sa supplements at timing, dapat mo talaga i-check with your OB, bawat pregnancy is different, at sila lang ang makakasabi kung okay for you yun at anong oras best. One of my mum friends din nag-take ng calcium but her doctor adjusted the timing based sa ibang vitamins niya, kaya really important to ask! Your OB will make sure everything works together perfectly para sa baby at sa'yo. Sending you love, mama, exciting na November!
