Week Of Pregnancy
Pregnancy Week By Week
Executive Summary By Robert Grazian
A very important time in the life of a woman is the period of pregnancy. She expects a nice cute baby with much anxiety and happiness. The waiting period is extremely enjoyable and anxious. There are many guides, calendars and tracking tools, which give much information on baby’s growth week by week and also various early symptoms of pregnancy. The general trends of the growth and movements can be easily described with these three time periods.
Pregnancy period always start with the date of last menses period. From that day to two period is the period of fertilization. During this period sperm fertilizes the egg. By the end of the two months, the baby’s sex can be determined using modern scanning facilities and a little baby has already taken shape. By week 14, first development period for the baby comes to an end and the mother gets secondary feelings such as blackening and itching around the nipples.
By week 1, the movements of the baby start. By week 17, the baby begins sucking and swallowing. By the half of the pregnancy period, say by week 20, the baby starts sleeping in regular times. Last period from week 27 to delivery. By week 27 the baby movements become very faster and mother feel the kicking of the baby in her stomach? The baby gets all his senses developed fully by week 30. Baby can hear, taste and smell from this week onwards. Also it provides the expected movements of the child during the pregnancy period.
Pregnancy Week By Week
Executive Summary By Beverley Brooke
There are three stages of pregnancy. It’s the stage where your body prepares itself by ovulating. The inner cells will form your baby and the outer cells will form the placenta. The implantation begins as the cell ball reaches the wall of the uterus. The implanted cell ball now becomes an embryo.
The amniotic sac and cavity begin to develop and also the Yoke sac appears (this will later form the baby’s digestive system). Week 5: The primitive streak (the fore runner of the brain and spinal cord) is now developing. Through this primitive streak the cells will develop into three layers:
The endoderm: the bottom layer – develops the glands, lung linings, tongue, bladder, digestive tract, tonsils, urethra and associated glands.
The mesoderm: the middle layer – forms the muscles, bones, heart, lungs, spleen, blood cells, and the reproductive and excretory systems.
The ectoderm: the top layer – forming the skin, nails, hair, eye lens, nose, mouth, anus, tooth enamel, pituitary gland, mammary glands, and all parts of the nervous system.
Other cells will be starting to develop the spine (called the notochord). The first steps towards forming the embryos head, and the first formation of the babies blood cells happen this week.
Week 6: The first few days of this week is when your baby’s heart starts beating. By mid week many organs are starting to form: eyes, arm buds, liver, gall bladder, stomach and intestines, lungs and pancreas.
Week 7: This is a busy week for your growing baby. During this week your baby will double in size. The lenses of the eyes are developing and there is also a recognisable tongue. Also hand and foot plates, elbow and wrist areas are forming. The heart is now starting to develop the four chambers.
Week 9: Your baby is now starting to form cartilage and bones. Also the baby is now becoming more active.
There is a fully formed upper lip. By mid week the earlobes are fully formed. Toes start to develop on the foot plate. Your baby’s body starts to straighten. This stage is where the baby starts to show individuality, as the muscle structure varies in each baby.
Week 12: Your baby will start to develop fingernails over the next three weeks. Also the baby will now be opening and closing its mouth.
Your baby’s heart beat will now be able to be heard using a Doppler. Baby’s hand also becomes more functional.
Week 15: The baby’s neck is now defined, with the head now resting on the neck rather than the shoulders. The hair pattern of the baby will be defined by the 102nd day of the pregnancy your baby will now be able to turn its head, open its mouth, kick, press its lips together and turn its feet.
Week 16: This week the baby’s toe nails will start to grow. The muscles will be growing stronger and the neck and head are growing straighter. Week 17: Your baby will be working on more reflexes this week; blinking, sucking, and swallowing. Through the course of this month your baby’s weight will increase 6 times.
Week 18: By mid week your baby’s eyes and ears will now be in the right places. The finger tips and toes will develop pads, and toe and finger prints will start to develop later in the week. Also by the second day of this week meconium (faecal waste) will start developing in the baby’s bowels.
Week 19: A creamy looking substance that covers the baby’s body, vernix coseosa, will start to form. This protects the baby and its developing glands and sensory cells. If you’re having a baby girl primitive egg cells are now developed in the ovaries, in fact females are born with all the eggs their ovaries will ever have.
Your baby will be waking and sleeping, just as newborns do. Baby’s leg and arm movements increase as the muscles and bones become stronger. The size of the baby’s body will start to get into proportion though the head will remain larger than the rest of the body.
Week 24: The skin of your baby is wrinkled, but will smooth out as fat is deposited. Week 25: Baby’s skin is now turning a reddish/pink as capillaries start to develop. The lungs will start developing blood vessels and the finger and toe nails will now be covering half the nail bed.
Baby’s lungs are growing rapidly and there is continual development with brain patterns.
Muscle tone is improving, and the lungs are capable of breathing air. The chances of a baby being born premature from now on, has a greatly improved chance of surviving.
Week 29: Eye lashes have now grown, and although still unable to focus, baby’s eyes are now sensitive to dark and light. At this stage of pregnancy the senses of sound, smell and taste are developing. Week 30: Baby is now storing up nutrients taken in by you. Calcium for skeletal development, protein for growth and iron for blood cells. Week 32: The baby’s iris is now reacting to light. All five senses are now registering with your baby, although smell is limited as baby can’t breathe air in the uterus.
Week 33: your baby may now be sucking its fingers. Week 35: In baby boys the decent of the testes will complete any time now. The baby is practising being more aware of its surroundings; this is the ‘orientating response’. This is where the baby will turn towards any source of light. Your body will be giving the baby antibodies so it can protect its self from many diseases. The baby will finish dropping into its resting place before birth.
