Your Body at 28 Weeks Pregnant
As you start the third trimester, keep in mind that you and your baby still have some growing to do. Your expanding belly bump at 28 weeks pregnant may get in the way at times, and throughout the remaining weeks of pregnancy, you might find yourself getting tired more easily. Your body is doing a great (and tough) job of providing a home for your little one as they continue to grow and develop during these final months and weeks. Continue paying attention to your diet by eating healthy, nutritious meals and snacks. Eating well may also help keep your energy levels up if you’ve been feeling worn out. If this is recommended by your healthcare provider, take prenatal vitamins or supplements to make sure you’re getting enough calcium and iron. Finally, continuing to exercise (moderately, and as your healthcare provider suggests) will help boost sagging energy levels. If you’re concerned about your weight gain at 28 weeks pregnant, check in with your provider to make sure your weight is increasing at a healthy rate.
