The normal fetal skeleton has accreted about 30 g calcium by the end of gestation, but about 80% of the accretion occurs rapidly during the third trimester. This corresponds to a daily accretion rate of about 250–300 mg calcium by the fetal skeleton during the third trimester.
Do calcium needs increase during pregnancy?

Why does pregnancy increase calcium?
Intestinal absorption of calcium doubles as early as 12 weeks of human pregnancy, as shown by clinical studies that used stable isotopes of calcium, and by other calcium balance studies (1). This increase in calcium absorption appears to be the major maternal adaptation to meet the fetal need for calcium.
Can pregnancy affect calcium levels?
A study found that pregnant women with the lowest levels of calcium (among those on normal diet and calcium supplements) also had the highest levels of lead in the blood. During pregnancy, hypocalcemia speeds up the production of new bone to replace old, dying bone.
