28 Weeks Pregnant: What's Going On

Pregnancy week 28

Brain wave patterns show that your baby can respond to sounds such as your voice, your tummy rumbling, and even noises in the outside world. Learn more about pregnancy week 28.

Your Baby at 28 Weeks Pregnant

Last week, your baby opened his eyes for the first time in four months, and he began to see light and shadows. This week, if you shine a bright light against your abdomen, he may open his eyes and turn away from the light.  

Loud and clear. Your baby's brain wave patterns  indicate that he's responding to sounds in the environment, such as sound of your voice, the growl of your stomach when you're hungry, even noises outside your body. The patterns are also starting to show differences during sleep. These sleep cycles will become clearer and more distinct closer to his due date. 

Breathe easy. This is a vital stage in your baby's lung development. When he takes his first breath, his lungs will send oxygen to the blood vessels, which then circulate it throughout his body. Your baby is also manufacturing a substance called surfactant to keep the air sacs in his lungs from sticking together, which will allow him to breathe properly after birth. The bronchial tubes are maturing, dividing into smaller and smaller branches. 

Measuring up. Your baby is gaining weight rapidly now — he may weigh about 2.3 pounds. Crown to rump, he measures 10 inches, but if you were to stretch him out he might be around 15 inches long.

Rh follow-up. If preliminary blood tests showed that you're Rh negative, you'll be given a shot of Rh immune globulin this week in case your baby is Rh positive. This will keep your body from producing antibodies to any of your baby's blood cells that may have crept into your circulation. Your baby will be tested right after birth; if she’s positive, you'll be given another shot of Rh immune globulin to protect future pregnancies. 

The mark of pregnancy. As your pregnancy progresses, stretch marks may appear on your abdomen, breasts, hips, and thighs. Most experts agree that there's not much you can do to avoid getting stretch marks, but applying cream or oil wouldn't hurt. Chalk it up to genetics — if your mother got them, you'll probably get them too. The good news? Stretch marks usually fade after birth. 

Two left feet. Your shifting center of gravity, along with your loosened joints, can make for a lot of bumping into tables and tripping over your own toes. Try and limit the spills by wearing flat shoes and slowing down.
