Mommy, please check with your OB-GYN about the right timing and dose of calcium para sa iyo, bawat pregnancy ay different, at sila lang ang makakasiguro ng safe schedule for you at baby! A few of us moms swear na importante talaga ang calcium throughout pregnancy, but honestly, timing and amount really depend sa doctor's assessment ng health mo. Kung binigyan ka ng prescription, siguraduhin lang na regularly mo siyang iinom as prescribed, at tanungin mo rin kung pwedeng i-pair with other vitamins para mas effective! Take care, mommy!
