hi, iam 18 weeks pregnant, my first trimester was from hell, iwas barely eating because of the nausea and exttreme fatige. ifeel better now but i know that the first trimester is so sensetive because most of the sensetive developing stages of my baby were taaking place by that time and am afraid my lake of eating may affect my baby (i wasnt on any parental vit. except folic acid). my last parental visit my DR. told me that my baby is smaller than he should be,that was month ago. and she highly reccomended that i should eat more specially foods with calcium. hopefully i did. but can all this lead to premature labour? and shold i take parental vit. although my DR. told me not to? and dose it help or replace the gap of my poor calcium diet?
