DOC I AM PREGNANT 2
Pregnancy is typically broken into three periods, or trimesters, each of about three months.
First Trimester:
The first 12 weeks of pregnancy are considered to make up the first trimester.
The first two weeks are the two weeks before conception.
The third week is the week in which fertilization occurs.
In the 4th week, the fertilized egg reaches the uterus and burrows into its wall which provides it with the nutrients it needs. At this point it is called an embryo which connects via the umbilical cord to the placenta in the wall of the womb.
The 5th week marks the start of the development of the embryo.
This is the time when the embryo's brain, spinal cord, heart and other organs begin to form.
At this point the embryo is made up of three layers,
1.the top one (called the ectoderm) will give to the embryo's layer of skin, central and peripheral nervous systems, eyes, inner ear, and many connective tissues
2.the middle layer (the mesoderm) will give rise to the heart and the beginning of the circulatory system as well as the bones, muscles and kidneys.
3.the inner layer (the endoderm) will give rise to the development of the lungs, intestine and bladder.
In the 6th week, the embryo will be developing basic facial features
Its arms and legs also start to grow.
In the 7th week, the brain, face and arms and legs quickly develop.
In the 8th week, the embryo starts moving
In the next 3 weeks, the embryo's toes, neck and genitals develop as well.
By the end of the first trimester, the fetus will be about 3 inches (76 mm) long and will weigh approximately 1 ounce(28g).
Second trimester
Weeks 13 to 28 of the pregnancy are called the second trimester.
Most women feel more energetic in this period, starting to put on weight as the symptoms of morning sickness fade away.
The movement of the fetus, often referred to as "quickening", typically happens in the fourth month, and can be felt in the 20th to 21st week, or earlier if the woman has been pregnant before.
The placenta fully functions at this time and the fetus makes insulin and urinates.
The reproductive organs differentiate the fetus as male or female.
Third trimester
Final weight gain takes place from the 29 to 40 weeks of pregnancy.
The fetus will be growing the most rapidly gaining up to 28 g per day.
The woman's belly will transform in shape as the belly drops due to the fetus turning in a downward position ready for birth.
Fetal movement can become quite strong and can be uncomfortable to the woman.
This period of her pregnancy can be uncomfortable, causing symptoms like weak bladder control and backache.
Movement of the fetus becomes stronger and more frequent.
There is head engagement ( the fetal head descends into the pelvic cavity) so that only a small part can be felt abdominally.
The perenium and cervix are further flattened and the head may be felt vaginally.
Because the head engagement severely reduces bladder capacity, increases pressure on the pelvic floor and the rectum,the
mother may experience the perpetual sensation that the fetus will "fall out" at any moment.
Childbirth
This is the process whereby an infant is born.
It is considered to be the beginning of the infant's life.
A woman is considered to be in labour when she begins experiencing regular uterine contractions, accompanied by changes of her cervix — primarily effacement and dilation. There may be waterbag bursting or blood(show)
Most childbirth is widely regarded as painful, some women do report painless labours
Most births are successful vaginal births, but sometimes complications arise and a woman may undergo a cesarean section.
During the time immediately after birth, both the mother and the baby are hormonally cued to bond, the mother through the release of oxytocin, a hormone also released during breastfeeding.
