week 7
Your 7-week embryo is generating about one hundred new brain cells each minute! And not only is baby's brain becoming more complex, but the heart is too. ... There are symptoms of twin pregnancy at 7 weeks besides seeing two gestational sacs on an ultrasound. -
week 12
Your little one's teeny toes can curl, her brain is growing furiously, and her kidneys are starting to excrete urine.The most dramatic development this week: reflexes. Your baby's fingers will soon begin to open and close, his toes will curl, his eye muscles will clench, and his mouth will make sucking movements. -
week 17
Your baby's skeleton is changing from soft cartilage to bone, and the umbilical cord is growing stronger and thicker.Your baby weighs 5 ounces now (about as much as a turnip), and she's around 5 inches long from head to bottom. She can move her joints, and her sweat glands are starting to develop. -
week 22
Your baby is starting to look like a miniature newborn. And your growing belly may be turning into a hand-magnet. -
week 27
This week, your baby weighs almost 2 pounds and is about 14 1/2 inches long with her legs extended. She's sleeping and waking at regular intervals, opening and closing her eyes, and perhaps even sucking her fingers. With more brain tissue developing, your baby's brain is very active now. While her lungs are still immature, they would be capable of functioning – with a lot of medical help –if she were to be born now. -
week 32
By now, your baby weighs 3 3/4 pounds and is about 16.7 inches long, taking up a lot of space in your uterus. You're gaining about a pound a week and roughly half of that goes right to your baby. She'll gain a third to half of her birth weight during the next 7 weeks as she fattens up for survival outside the womb. She now has toenails, fingernails, and real hair (or at least respectable peach fuzz). Her skin is becoming soft and smooth as she plumps up in preparation for birth. -
week 37
our due date is very close now, but doctors don't consider your baby "full term" until 39 weeks. Many babies have a full head of hair at birth, with locks from 1/2 inch to 1 1/2 inches long. But don't be surprised if your baby's hair isn't the same color as yours. Dark-haired couples are sometimes thrown for a loop when their children come out as blonds or redheads, and fair-haired couples have been surprised by Elvis look-alikes. -
week 40
Your baby is the size of a small pumpkin! Don't worry if you're still pregnant – it's common to go past your due date.It's hard to say for sure how big your baby will be, but the average newborn weighs about 7 1/2 pounds (about the size of a small pumpkin) and is about 20 inches long. Her skull bones are not yet fused, which allows them to overlap a bit if it's a snug fit through the birth canal during labor. -
week 2
You become pregnant near the end of week two or the beginning of week three, depending on when your body ovulates. Ovulation marks your body's fertile period.
