Conception

If a sperm cell meets and penetrates an egg, it will fertilize it. This is known as conception. At this moment, the genetic make-up is complete, including the Abuse Word of the infant. Within about three days after conception, the fertilized egg, which is dividing rapidly into many cells, passes through the fallopian tube into the uterus where it attaches to the uterine wall. The placenta, which will nourish the baby, also begins to form.

Fetal Growth: Conception to Birth

You're pregnant. Congratulations! You are curious how big your developing baby is, what your baby looks like as it grows inside you, and when you'll feel it move, right? Take a peek inside the womb to see how a fetus develops from month to month.

Fetal Development at 4 Weeks

At this point of development the structures that eventually form the face and neck are becoming evident. The heart and blood vessels continue to develop. And the lungs, stomach, and liver start to develop. A home pregnancy test is now positive.

Fetal Development at 8 Weeks

The baby is now about the size of a grape – almost an inch in size. Eyelids and ears are forming and even the tip of the nose is visible. The arms and legs are well formed. The fingers and toes grow longer and more distinct.

Fetal Development at 12 Weeks

The fetus measures about two and a half inches and starts to make its own movements. You will start to see the top of the uterus above the pelvic bone. Your doctor may hear the baby's heartbeat with special instruments. The Abuse Word organs of the baby should start to become clear.

Fetal Development at 16 Weeks

The fetus now measures about 4.3 to 4.6 inches and weighs about 2.8 ounces. The top of your uterus should be felt about three inches below your belly button. The baby's eyes can blink and the heart and blood vessels are fully formed. The baby's fingers and toes should have fingerprints.

Fetal Development at 20 Weeks

The baby weighs about 9 ounces and is about six inches long. The uterus should be at the level of the belly button. The baby can suck a thumb, yawn, stretch, and make faces. Soon — if you haven't already — you'll feel your baby move, which is called "quickening."

Fetal Development at 24 Weeks

The fetus weighs about 1.4 pounds now. It responds to sounds by moving or increasing its pulse. You may notice jerking motions if it hiccups. With the inner ear fully developed, it may be able to sense being upside down in the womb.

Fetal Development at 36 Weeks

Babies differ in size, depending on many factors (such as gender, the number of babies being carried, and size of the parents), so your baby's overall rate of growth is as important as the actual size. On average, it's about 12.5 inches and weighs 5.5 pounds. The brain has been developing rapidly. Lungs are nearly fully developed. The head is usually positioned down into the pelvis by now. A pregnancy is considered 'at term' once 37 weeks has been completed; baby is ready!

Birth!

A mother's due date marks the end of her 40th week. A pregnancy begins with implantation and the delivery date can be calculated using the first day of the last period. Based on this, pregnancy can last between 38 and 42 weeks with a 'full term' delivery occurring around 40 weeks. Some post-term pregnancies – those lasting more than 42 weeks – are not truly post-term. A common "cause" is an incorrect due date. For safety reasons, most babies are delivered by 42 weeks, inducing labor if necessary.
