I craved ice w/all 3 babies but only when pregnant.last couple of weeks craving ice, def not preg.recent blood work says not anemic.any other causes?

Other minerals?: That craving is called pica, which is associated with iron deficiency, but there could be another mineral that you need. You may want to try taking a good organic mineral supplement.

Can be iron-low: Iron deficiency and pica can and do precede anemia -- I learned this from personal experience as a blood donor who neglected oral iron supplementation.
