Detailed Description

The primary outcome is the incidence of hypocalcemia among pregnant women in the first half of pregnancy. This study also has secondary objectives. The one is associating factors with calcium level. After getting the results of maternal calcium level, the normal calcium level group will be divided into 2 groups for receiving calcium 1 g/day and no receiving calcium supplement. Another with hypocalcemia group will be decided into 2 groups for receiving calcium 1 g/day and 2 g/day. The calcium level was collected again in the third trimester.

In the normal calcium level group, pregnant women will be divided into 2 groups: receiving CaCO3 1 g/day and no receiving.
