Week 1
week 1No, there’s no baby or even an embryo in sight (at least not yet). But in week two of pregnancy, your body is working hard to gear up for the event that paves the way for the baby: the big O — ovulation. The lining of your uterus is thickening, preparing for the arrival of a fertilized egg, and your ovarian follicles are maturing. One of those follicles will release the egg that will travel down the fallopian tube in search of the lucky sperm that will turn that eager egg into a baby. -
Week 6
You might be coping with full-blown pregnancy symptoms, but there's plenty of good news too. Your baby's jaw, cheeks, chin, eyes, ears, and nose are beginning to form what will eventually become one adorable face. In addition, her kidneys, liver, and lungs are developing, and her heart is now beating 80 times a minute and getting faster every day. All this and she's still no bigger than about a quarter of an inch from crown to rump! -
Week 10
Week 10Your baby (now the size of a prune) has small indentations on his legs (soon to be knees and ankles!), and his tiny arms even have elbows that bend. Inside that little mouth, tiny buds of baby teeth are forming under the gums. His stomach and kidneys are kicking into gear, producing digestive juices and urine, and if it's a boy, his testes are making testosterone. -
Week 14
Now the size of your clenched fist, your baby is more fluid-like in his movements, so he’s no longer jerking every time he repositions his arms and legs. Other developments this week include a roof of his mouth, as well as intestinal activity: His intestines are producing the waste that will make up his first bowel movement after birth. He is also sporting a downy coating of hair that keeps him nice and warm. Then baby fat will accumulate over the next few months and start keeping your baby warm -
Week 18
There is worse pregnancy back pain but your baby's getting ready to move. At five and a half inches long and five ounces in weight, he now may be large enough for you to feel him twisting, rolling, kicking, and punching his way around the womb, he's also developing yawning and hiccupping skills and his own unique set of toe and fingerprints. -
Week 21
Your baby is about the size of a large banana there's a good chance your baby will get a taste what you eat. That's because he swallows a bit of amniotic fluid each day for nutrition, hydration, and to practice digesting, so he eats whatever you did, he's using his developing taste buds. -
Week 25
Your baby is growing quickly, reaching nine inches in length and passing the pound and a half mark. Under his skin, capillaries are forming and filling with blood and by week's end, air sacs will develop in his lungs, getting them ready for that first breath. Those lungs aren't ready just yet but they are a substance that will help them expand after birth. And your baby's tiny nostrils, which have been plugged up until now, are starting to open, and his vocal chords are getting ready. -
Week 29
This week she weighs nearly three pounds now and measures about 17 inches. Though she's getting pretty close to her birth length. In fact, over the next 11 weeks, she'll more than double or close to triple her weight. And as she grows and the room in your womb gets tighter, you'll be less likely to feel those big kicks and more likely to get poked by an elbow or jabbed by a knee. -
Week 34
Your baby is about five pounds and could be as tall as 20 inches by now, and the white coating protecting your baby’s skin is getting thicker. This week, a boy's testicles start making their way down from his abdomen to their final destination: his scrotum. While about three to four percent of boys are born with undescended testicles, they usually move down before he turns a year old. In other developments, his tiny fingernails have reached the tips of his fingers by now. -
Week 37
You've got what is considered a full term baby even with three weeks left. That doesn't mean he's finished growing, he's still gaining about a half pound a week the average fetus weighs about 6.5 pounds at this age. That makes it tight in your uterus, so he’s not kicking, probably stretching, rolling a bit, and wiggling. Right now he is inhaling and exhaling amniotic fluid to get the lungs ready for that first breath, sucking his thumb to prepare for his first suckle of milk, and blinking
