Development Of Conception Period






The prenatal period(After Conception)the baby begins to grow and development.Life begins at the moment of cocception. Merwdth has reported that the average length of prenatal period is 38 weeks or 266 days.70% of babies vary from36 to 40 weeks(252 to 280 days)and 98% 34 to 42 weeks(238 to 294 days). prenatal develomment is orderly and predictable,the importent developments taking placc during this period.


The first two weeks after conception are known as the germinal stage, the third through the eighth week is known as the embryonic period, and the time from the ninth week until birth is known as the fetal period.
After fertilization and implantation, a baby is at first just an embryo: two layers of cells from which all the organs and body parts will develop. Growing quickly, your baby is soon about the size of a kidney bean and constantly moving. The heart is beating quickly and the intestines are forming. Your budding son or daughter's earlobes, eyelids, mouth, and nose are also taking shape.

Germinal Stage (first 2 weeks) 

Egg

2 weeks pregnant.
It's a potentially life-changing week. You'll ovulate, and if egg meets sperm, you'll be on your way to pregnancy!


Embryonic period(3 to 8 weeks) 


Blastocyst  

3 weeks pregnant.
Your baby is a tiny ball – called a blastocyst – made up of several hundred cells that are multiplying quickly.

Embryo at 4 weeks

4 weeks pregnant.
Deep in your uterus, your baby is an embryo made up of two layers, and your primitive placenta is developing.

Your tiny embryo is growing like crazy, and you may be noticing pregnancy discomforts like sore breasts and fatigue.

Your little one's teeny toes can curl, her brain is growing furiously, and her kidneys are starting to excrete urweeks


Baby in utero at 13 weeks

13 weeks pregnant.
It's the last week of the first trimester! Your baby now has exquisite fingerprints and is almoses long.

Second trimester
This middle section of pregnancy is often thought of as the best part of the experience. By this time, any morning sickness is probably gone and the discomfort of early pregnancy has faded. The baby will start to develop facial features during this month. You may also start to feel movement as your baby flips and turns in the uterus. During this trimester, many people find out the sex of the baby. This is typically done during an anatomy scan (an ultrasound that checks your baby’s physical development) around 20 weeks.

Month 4 (weeks 13 through 16)

Your baby's heartbeat may now be audible through an instrument called a doppler. The fingers and toes are well-defined. Eyelids, eyebrows, eyelashes, nails and hair are formed. Teeth and bones become denser. Your baby can even suck his or her thumb, yawn, stretch and make faces.

The nervous system is starting to function. The reproductive organs and genitalia are now fully developed, and your doctor can see on ultrasound if you are having a boy or a girl.

By the end of the fourth month, your baby is about 6 inches long and weighs about 4 ounces.

Month 5 (weeks 17 through 20)

At this stage, you may begin to feel your baby moving around. Your baby is developing muscles and exercising them. This first movement is called quickening and can feel like a flutter.

Hair begins to grow on baby's head. Your baby's shoulders, back and temples are covered by a soft fine hair called lanugo. This hair protects your baby and is usually shed at the end of the baby's first week of life.

The baby's skin is covered with a whitish coating called vernix caseosa. This "cheesy" substance is thought to protect your baby's skin from the long exposure to the amniotic fluid. This coating is shed just before birth.

By the end of the fifth month, your baby is about 10 inches long and weighs from 1/2 to 1 pound.

Month 6 (weeks 21 through 24)

If you could look inside the uterus at your baby right now, you would see that your baby's skin is reddish in color, wrinkled and veins are visible through the baby's translucent skin. Baby's finger and toe prints are visible. In this stage, the eyelids begin to part and the eyes open.

Baby responds to sounds by moving or increasing the pulse. You may notice jerking motions if baby hiccups.

If born prematurely, your baby may survive after the 23rd week with intensive care.

By the end of the sixth month, your baby is about 12 inches long and weighs about 2 pounds.

Month 7 (weeks 25 through 28)

Your baby will continue to mature and develop reserves of body fat. At this point, the baby's hearing is fully developed. The baby changes position frequently and responds to stimuli, including sound, pain and light. The amniotic fluid begins to diminish.

If born prematurely, your baby would be likely to survive after the seventh month.

At the end of the seventh month, your baby is about 14 inches long and weighs from 2 to 4 pounds.

Third trimester
This is the final part of your pregnancy. You may be tempted to start the countdown till your due date and hope that it would come early, but each week of this final stage of development helps your baby prepare for childbirth. Throughout the third trimester, your baby will gain weight quickly, adding body fat that will help after birth.

Remember, even though popular culture only mentions nine months of pregnancy, you may actually be pregnant for 10 months. The typical, full-term pregnancy is 40 weeks, which can take you into a tenth month. It’s also possible that you can go past your due date by a week or two (41 or 42 weeks). Your healthcare provider will monitor you closely as you approach your due date. If you pass your due date, and don’t go into spontaneous labor, your provider may induce you. This means that medications will be used to make you go into labor and have the baby. Make sure to talk to your healthcare provider during this trimester about your birth plan.

Month 8 (weeks 29 through 32)

Your baby will continue to mature and develop reserves of body fat. You may notice that your baby is kicking more. Baby's brain is developing rapidly at this time, and your baby can see and hear. Most internal systems are well developed, but the lungs may still be immature.

Your baby is about 18 inches long and weighs as much as 5 pounds.

Month 9 (weeks 33 through 36)

During this stage, your baby will continue to grow and mature. The lungs are close to being fully developed at this point.

Your baby's reflexes are coordinated so he or she can blink, close the eyes, turn the head, grasp firmly, and respond to sounds, light, and touch.

Your baby is about 17 to 19 inches long and weighs from 5 ½ pounds to 6 ½ pounds.

Month 10 (Weeks 37 through 40)

In this final month, you could go into labor at any time. You may notice that your baby moves less due to tight space. At this point, your baby’s position may have changed to prepare for birth. Ideally, the baby is head down in your uterus. You may feel very uncomfortable in this final stretch of time as the baby drops down into your pelvis and prepares for birth.
Your baby is ready to meet the world at this point.

Your baby is about 18 to 20 inches long and weighs about 7 pounds.
