- 1Baby’s Development. Welcome to the third trimester! Your baby is around 2.25 pounds and 10 inches crown-to-rump. They can open and close their eyes, regulate body temperature, and are becoming more active. Position may be head-down or breech but can still change in the coming weeks
- 2Bodily Changes & Symptoms. Your bump is growing, and fundal height is usually around 28 cm. Common symptoms include back or pelvic pain, shortness of breath, hemorrhoids, Braxton Hicks contractions, and frequent urination. Supportive shoes, posture, hydration, fiber, and rest can help.
- 3Health & Wellness. Begin daily kick counts—aim to feel about 10 strong movements within 2 hours during baby’s active times. Kegels, supportive sleep positions, and pacing your nesting can all ease this stage. Always contact your provider if fetal movement decreases noticeably.

How Many Months Is 28 Weeks Pregnant?

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, 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.
