At around 5 months into the pregnancy, my nails began to grow out
a complete opaque white from the root, (they did not turn white, and they grew out
white). I began taking my vitamins, and the nails slowly grew back normally. At the time no renal or liver abnormalities on blood work, Dr. said it was nothing to worry about. Problem resolved. About six months later after chronic severe stress, I began to have some white lines grow again, not uniformed on several nails.
