Pay attention to your diet. Exercise consistently. Drink enough water.
Part of looking beautiful while pregnant is gaining the necessary amount of weight to properly nourish your baby. Pregnant woman should eat between 2000 and 2500 calories each day, spread throughout 4 meals. Paying attention to your caloric intake will help you avoid gaining unnecessary weight that may put you at risk for certain medical conditions. You should gain the weight necessary to provide adequate nutrition for your baby and to allow him to grow to a healthy size, but you should pay close attention to  gaining the appropriate amount of weight, which will keep you feeling beautiful throughout all three trimesters of your pregnancy. If you have gained more weight then you planned (or more than your doctor deems healthy) you may need to lose weight. It is important to take great caution when attempting to lose weight while pregnant to ensure that your weight loss does not negatively affect your baby. If consistent exercise made you feel confident and beautiful before your pregnancy, there is no reason that pregnancy should force you to stop (although you may need to alter your workout routine). Feeling fit and strong will make you feel more confident about the way you look and will also help in getting you pre-pregnancy body back after you give birth. Getting exercise during your pregnancy will help you keep your weight down, will boost your mood and energy level, and will increase your stamina and muscle strength. Together, these positive results will help you to feel more beautiful.  Consider attempting to get 30 minutes of moderate exercise most days of the week. Walking, aerobics, and swimming are all great low-impact activities that you may want to try during your pregnancy. These activities will help you stay in shape and feel beautiful. Always confer with your doctor before starting a workout routine when pregnant. There are certain situations, such as if you have pregnancy-related high blood pressure, in which your doctor may advise you not to exercise. Dehydration is a very real risk during pregnancy, and drinking enough water will help you feel healthy and look beautiful. While a person should attempt to drink roughly one-half to one ounce of water for each pound that he weighs every day, a pregnant woman must pay even more attention to her water intake. Water helps form the placenta and is used in the amniotic sac in your pregnancy. In addition, not drinking enough water can have a negative effect on your appearance. Dehydration can make your skin look dull, negating the beautiful glow that will accompany your pregnancy. In addition, dehydration can make you feel sluggish and ill, and it is hard to look beautiful when you are not feeling up to par. It is recommended that pregnant women drink about 10 cups (or 2.3 liters) of fluids daily. Drinking water for the majority of this requirement will help you avoid the sugars present in fruit drinks and sodas.
