Today i went in for my preconception appointment. i absolutely love the OB, i feel so comfortable with her!! She prescribed me a prenatal vitamin, but when i went to Walgreens to get the prescription, the total price was $45.00!! Usually my Rx are like 4.00. Should i take an OTC one, are those as good as the Rx ones?? What are the best OTC brands and what are the prices??
