I've started using Chela Preg since the day I found out I was pregnant (5 weeks). I am now in my third trimester and this is the only pre-natal vitamin I've used throughout my pregnancy, which obviously means I used all 3 trimester packs.
I've hardly felt any fatigue symptoms the past few months, and only experienced mild constipation once or twice. What makes me happy is that my doctor is extremely satisfied with my health and iron levels. I definitely recommend this product to all pregnant moms, I cannot imagine a pregnancy without this.
