28 weeks

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.

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. Try stretching or massaging your legs, and cut down on caffeine, which can make the symptoms worse.
