28 Weeks

How your baby's growing: By this week, your baby weighs two and a quarter pounds (like a Chinese cabbage) and measures 14.8 inches from the top of her head to her heels. She can blink her eyes, which now sport lashes. With her eyesight developing, she may be able to see the light that filters in through your womb. She's also developing billions of neurons in her brain and adding more body fat in preparation for life in the outside world.

How your life's changing: You're in the home stretch! The third and final trimester starts this week. If you're like most women, you'll gain about 11 pounds this trimester. At this point, you'll likely visit your doctor or midwife every two weeks. Then, at 36 weeks, you'll switch to weekly visits. Depending on your risk factors, your practitioner may recommend repeating blood tests. Around this time, some women feel an unpleasant "creepy-crawly" sensation in their lower legs and an irresistible urge to move them while trying to relax or sleep. If this sensation is at least temporarily relieved when you move, you may have what's known as restless legs syndrome (RLS). No one knows for sure what causes RLS, but it's relatively common among expectant mothers. Try stretching or massaging your legs, and cut down on caffeine, which can make the symptoms worse.
