How your baby's growing: This week's major developments: The nose, mouth, and ears that you'll spend so much time kissing in eight months are beginning to take shape. If you could see into your uterus, you'd find an oversize head and dark spots where your baby's eyes and nostrils are starting to form. His emerging ears are marked by small depressions on the sides of the head, and his arms and legs by protruding buds. His heart is beating about 100 to 160 times a minute — almost twice as fast as yours — and blood is beginning to course through his body. His intestines are developing, and the bud of tissue that will give rise to his lungs has appeared. His pituitary gland is forming, as are the rest of his brain, muscles, and bones. Right now, your baby is a quarter of an inch long, about the size of a lentil bean.

Surprising Facts: Could it be twins?
Sure, twins run in families and you're more likely to be carrying multiples if you've undergone fertility treatments, but any woman can become pregnant with more than one baby. Could you be one of them?
Your odds of carrying twins
* Overall, about one in 31 births (greater than 3 percent) are twin births. But your chances of having twins are much less — 1 in 89 — if you conceive without medical assistance. The overall odds of bearing triplets or higher-order multiples is about 1 in 565.
* Identical twins usually happen by chance. Your likelihood of having identical, or monozygotic, twins (when one fertilized egg divides in half) is about 1 in 250.
* A number of factors affect your odds of having fraternal twins or higher-order multiples. Fertility treatments dramatically increase your odds. On average, 20 to 25 percent of women who take fertility drugs or undergo in vitro fertilization or other assisted reproductive techniques end up carrying more than one baby.]
