Pescetarians eat vegetables, fruit, grains, and fish, and may or may not eat eggs and dairy products.  Because pescetarianism is not a vegetarian diet, you should not have unmet nutritional needs, unless you do not drink milk or eat a balanced diet.  A diet that does not contain dairy products could lack protein and vitamin D and would definitely fall short on calcium.  Girls need 1300 mg of calcium a day, which may be taken in the form of calcium supplements. Milk contains other nutrients too, but they are more widely available in foods.
