Prescription Prenatal Vitamins

Ja
So I went to my Obgyn yesterday and she sent me home with samples to try out. She said to let her know which I like and she will prescribe them. But I can't seem to find any updated reviews on them. I would like to know if any of you ladies have tried any of these and how you felt on them? Thanks 😃
