At five weeks, your embryo measures a mere two millimeters, but every organ is already under development. Even facial features, such as eyes and ears, begin to form. By the time you are six weeks along, you KNOW you are pregnant. It may be difficult to stomach those prenatal vitamins, but they are very critical at this stage of development. Prenatal vitamins contain many important nutrients, including folic acid.
