    Your baby’s development

    It’s graduation day. Your embryo is now a fetus.
    By week 10, all vital organs have formed, and your baby’s is now considered a fetus.* What are some other changes your baby is going through during your 10th week of pregnancy?

    By now your baby measures longer than 1 inch, or roughly the length of a quarter.

    By the end of the 1st trimester, his body will grow to about 3 inches — around the length of a kiwi fruit. This measurement doesn't count arms and legs, because in the 1st trimester, he is measured from the top of the head to the bottom of the rump.

    His embryonic tail, (Yes, he has a tail, located at the bottom of his spinal cord), has disappeared.

    At 10 weeks, his ears approach their final form. His teeth buds emerge, and his eyelids develop further.

    His testes start producing testosterone around the 10th week.

    Tiny fingers and toes, which were previously webbed, are now fully separated.

    Your nutrition and health

    There’s no beating healthy eating.
    At this stage of your pregnancy, by choosing good foods from all of the food groups, you're nourishing your baby with a broad range of different nutrients.

    • 6 ounces of breads and grains (1 slice of bread or ½ cup cooked rice/pasta counts as 1 ounce)
    • 5 ½ ounces of protein (meat and beans)
    • 3 cups of dairy products (1cup of milk, yogurt or fortified soymilk or 1 ½ ounces of natural cheese or 2 ounce of processed cheese counts as 1 cup)
    • 2 cups of fruit (fresh, frozen, or canned) (1 cup of raw or cooked fruit or 100% fruit juice; or ½ cup dried fruit counts as 1 cup)

    Things to think about now

    Buckle up, your hormones are driving.
    Not feeling quite like yourself these days? Hormones released by your placenta, ovaries, adrenal glands, and pituitary gland are not only guiding the growth of your baby, but are guiding changes within your own body as well.
