What are good prenatal vitamins to take im 5 weeks and 1 day pregnant?

Many good ones but.. There are many good prenatal vitamins. One of the most important ingredients is folic acid, proven to prevent neural tube defects, but I have become aware of research suggesting that synthetic Folic Acid may increase breast cancer risk. Safest choice may be one that provides the natural 5-mthf form of folate such as basic prenatal by thorne research and prenatal pro by designs for health.
