week 3
Your baby-in-the-making is a ball of cells called a blastocyst. -
week 4
The ball of cells has officially become an embryo and is about the size of a poppy seed -
week 5
Your baby's tiny heart begins to beat – at twice the rate of yours. His entire "body" is only about the size of a sesame seed. -
Week 6
Facial features (like eyes and nostrils) are beginning to form, and little buds appear where arms and legs will develop -
Week 8
Arms and legs are growing, and your baby now has little fingers, as well as a nose and upper lip. -
Week 9
Eyes have developed, though your baby's eyelids are fused shut for now. She's lost her "tail" and is starting to look more human. -
Week 10
The embryo has become a fetus. His vital organs – such as kidneys, intestines, brain, and liver – are starting to function. Tiny fingernails and toenails are forming. -
Week 11
Your baby is almost fully formed. Her bones are beginning to harden, and her genitalia are developing externally. She can hiccup, though it's too soon for you to feel it. -
Week 12
You can hear your baby's heartbeat at a prenatal checkup.(You may already have heard it at an early ultrasound.) Your baby's just over 2 inches long and weighs about half an ounce. -
Week 14
Your baby's kidneys are producing urine, and he releases it into the amniotic fluid. He can make facial expressions and may have discovered thumb-sucking. -
Week 15
Your baby can see light that filters in from outside your womb, even though her eyelids are still shut. -
Week 16
Your baby's sex may be detectable at your mid-pregnancy ultrasound, which typically happens between 16 and 20 weeks -
18 weeks
If you haven't felt your baby move yet, you probably will in the next few weeks. It'll take a couple of weeks longer for your partner and other people to feel your baby's movements from the outside. -
19 weeks
Your baby can hear your heartbeat and sounds that come from outside your body, such as your partner's voice. Your baby might even be startled by a loud noise. -

Gulping down several ounces of amniotic fluid each day -
22 Weeks

23 weeks
Your baby's sense of movement has developed, so he can feel the motion if you dance. His sense of hearing continues to improve. -
Week 24
Your baby's taste buds are developing. Her brain is growing very quickly, and her hair may be growing, too. -
Week 25
She's enjoying her new sense of equilibrium! She's growing more fat and more hair too! -
Week 27
Your baby's been doing "practice breathing" by inhaling and exhaling amniotic fluid, and if he was born now his lungs could function -

Your baby may be dreaming. She has eyelashes, and her eyesight is improving. She weighs about 2 1/4 pounds and is about 15 inches long, head to heel. -

He's grown cute little fingernails and toenails. He's almost 17 inches long (head to heel) and weighs about 3 3/4 pounds. -
Week 34
If your baby's born now, she's considered "late preterm." Healthy babies born at this stage usually do fine, though they need some care in the neonatal intensive care unit. -
