8 weeks pregnant

8 weeks pregnant: Below summarizes the various stages of pregnancy within the first trimester(8 weeks pregnant).

0-3 weeks pregnant

Your weeks of pregnancy is dated from the first day of your last period. This means that in the first two weeks or so, you’re not really pregnant – will prepare your body for ovulation as usual. You ovulate (release an egg) approximately two weeks after the first day of your period (depending on the length of your menstrual cycle).

During the third week after the first day of your last period, your fertilized egg moves down the fallopian tube to the uterus. The egg starts as a single cell, which divides again. When the egg reach the uterus,it has a mass of more than 100 cells, known to be an embryo. Once in the uterus, the embryo digs into the lining of the uterus. This is called implantation.

4 weeks pregnant

In weeks 4-5 of early pregnancy, the embryo grows and develops within the lining of the uterus. The outer cells reach out to form ties with the blood supply from the mother. The inner cells are in two forms, and later again, in three layers. Each of these layers will grow to be different parts of the body of the baby.
The inner layer, called endoderm, breathing and digestive system, including the lungs, stomach, intestines and bladder. The middle layer,are called the mesoderm, the heart, blood vessels, muscles and bones. The outer layer, called the ectoderm, the brains and the nervous system, the eye lenses, tooth enamel, skin and nails.

In these first weeks of pregnancy, the embryo is usually a small yolk sac that provides nutrition related or alternatives. A few weeks later, the placenta is fully formed and taking to move the transfer of nutrients to the embryo.

The embryo is surrounded by fluid in the amniotic sac. It is the outermost layer of the bag that develops in the placenta. Cells grow in the placenta deep into the lining of the uterus, which forms the creation of a rich blood supply. Because of this baby all the oxygen and nutrients it receives are necessary.

5 weeks pregnant

The fifth week of pregnancy is the time of the first missed period, when most women are just beginning to think they may be pregnant. But all the nervous system of the baby develops, and are the basis for the most important organs in place. At this stage embryo is about 2 mm long.

Since the ectoderm develops a groove forming layer and folded in the cells to a hollow tube, to form the neural tube. This will be the baby’s brains and spinal cord. Defects in the ‘tail’ of the neural tube lead to spina bifida, while defects in the “head end” lead to anencephaly (when the bones of the skull and the brains do not form good).

At the same time constitutes the heart which is a simple tube-like structure. The baby already has some of her own blood vessels and blood starts to circulate. A series of these blood vessels become connected to the baby and mother, and will be the umbilical cord.

6 weeks pregnant

By the time you are six to seven weeks pregnant, there is a large bulge at the heart and a bulge at the head end of the neural tube. This bump will become the brains and the head. The embryo is curved and has a tail – it looks a bit like a little tadpole. The heart can sometimes be seen beating in a vaginal ultrasound at this stage.

The development of arms and legs are visible as small swellings (limbs). Dimples on the side of the head, the ears, and there are bulges where the eyes will be. Meanwhile, the embryo is covered with a thin layer of clear skin.

7 weeks pregnant

Through seven weeks, the embryo has grown to about 10 mm long from head to toe. This measurement is called the “crown-rump length.” The brains is growing rapidly, and this results in the head faster than the rest of the body. The embryo has a large forehead, and continue to develop the eyes and ears. The inner ear begins to develop, but the auricle on the side of the head will not be develop in a few weeks.

The limbs go cartilage, which grow to form the bones of the legs and arms. The arm buds are longer and ends out flat- this will become the hands. Nerve cells continue to multiply and develop the nervous system (brains and spinal cord) is taking shape.

8 weeks pregnant

By the time you are now eight weeks pregnant, the baby is a fetus, which is usually called posterity. The legs are to extend and the cartilage formation begins as well. The different parts of the leg not previously been well understood – it will take a little longer time to develop the knees, ankles, thighs and toes. The fetus is still within its amniotic sac, placenta and continues to develop, the formation of structures called chorionic villi which help attach the placenta to the wall of the uterus. In this stage, the fetus still gets its power from the yolk sac.

YOU (8 weeks pregnant symptoms)

Fertilization usually occurs about two weeks after your last period, around the time you ovulate (release an egg). In the first four weeks of pregnancy you will probably not notice any symptoms. The first thing that makes most women is that their term or period does not arrive. Read more about the signs and symptoms of pregnancy.

Your uterus has grown to the size of a lemon by the time you are around seven or eight weeks pregnant. You’re probably tired. Your breasts may feel painful and extensive, and you’re likely to need to pass urine more often than usual.

Some pregnant women begin sick or tired, to feel some minor physical problems for a few weeks around this time. Most women stop having morning sickness and start to improve by the time they are about 14 weeks pregnant feel.
