Changes at 27 Weeks At 27 weeks, you may be fighting food cravings. Keep in mind that you only need 300–500 extra calories per day to remain healthy and to provide your baby with sufficient nutrients. As your uterus continues to grow and put pressure on your upper chest area, you may be experiencing chest pains or shortness of breath. This is normal, but talk to your healthcare provider about this issue if you are concerned. You may also be experiencing swelling in your face, neck, hands, feet, ankles, legs, and just about everywhere else. Try resting on your left side and relaxing as much as possible to help cope with this common pregnancy symptom. Baby’s Development As the end of the second trimester arrives, your baby should be close to 15 inches in length and weigh over two pounds. As the eyes continue to develop, the layers of the retina are forming, and the membrane that covers the eyes separates to form eyelids. You may notice that your baby is developing its own waking and sleeping patterns. This is normal, and many doctors suggest you try to rest as much as possible while the baby is resting. The tissues and grooves in your baby’s brain continue to form. Some experts believe that the baby begins to dream at this point, but there is no conclusive proof that this is happening. You may also feel your baby hiccuping as their lungs continue to mature and they inhale and exhale amniotic fluid.
