Pregnancy Week 0-4

Pregnancy Week 4

Mother

The symptoms are basically the same during all the first critical weeks. Some feel stabbing pain and discomfort at the bottom of the stomach, pain that can be reminiscent of common menstrual pain. Many people have virtually no pregnancy symptoms at all, and they sail through the first trimester without noticing the pregnancy. If you feel dejected and hopeless, this is nothing unusual during this period. The reason for this is all the hormones that ravage around you.

Pregnancy Week 0-4

The embryo

This week, the baby's heart starts beating, and towards the end of the week, the folic acid supplement you have started to take advantage of. Then the spine is formed, and the brain is split into two halves. The nerve tube closes on day 28. It is possible to see what is the head and what is the tail of the embryo, which is 1.5–2.5 mm long. The umbilical cord develops during this and next week. It handles the transport of nutrients and oxygen from the mother to the embryo.

Miscarriage Risk

It is not obvious that the embryo survives and becomes a fetus and later becomes a living child. For more information about pregnancy and maternity fashion, please see BESTAAH.COM maternity pants. Probably 50% of all conception ends with a miscarriage, but most do not notice any noticeable changes in subsequent menstruation and can only be measured by careful HCG analysis. Therefore, you will not notice that you have been pregnant.

Until the end of week 16, the risk of miscarriage is higher. It is estimated that miscarriages occur in 10-15% of all known pregnancies. Almost all miscarriages (miscarriages) occur before week 16.

Bleeding during pregnancy is not uncommon.

Pregnancy and smoking

Most of what you breathe in reaches the fetus via the placenta. This applies to both beneficial and harmful substances. The carbon monoxide in the cigarette smoke pushes the oxygen away from the red blood cells and causes the fetus to suffer from slight oxygen deficiency all the time. The nicotine in the tobacco causes the blood vessels to contract so that the blood supply to the child becomes worse. These, and many other substances in the smoke, make the child less equipped to cope with stress.

Pregnancy Week 3

Mother

Now you can test positive in a pregnancy test. It is the levels of the pregnancy hormone HCG that give rise to the urine test. Maybe the first pregnancy symptoms start to appear. You may need to urinate more often, you may feel tired and nauseous and may have swollen breasts. Neither is it strange or unusual to suffer from mood swings. After all, the body has begun to work on a large and demanding task.

Avoid staying in environments that can be harmful to you and the child. It's not just about avoiding alcohol and drugs yourself, but also avoiding things like passive smoking, contact with harmful chemicals, pesticides, X-rays, colorways, and large amounts of coffee.

A mucus in the cervix protects against external infections, so you don't have to be afraid to bathe, go to the swimming pool or have intercourse.

The embryo

The child already has skin, intestinal tract, lungs, nervous system, muscles and blood vessels. Now the blood flow from you to the embryo has been established. Embryo is what you call the baby in this early phase.

Iron needs during pregnancy

It has been found that the need for iron increases during pregnancy. The fetus should have one part and another part needed in the placenta. In addition, blood volume increases, and this also requires some iron. In total, the need for iron is at least double that of pre-pregnancy.

Pregnancy Week 2

The fertilized egg travels through the fallopian tube before it enters the uterine wall. The egg attaches to the uterine wall about seven days after conception. The cell division started as soon as the egg was fertilized. The child is now about the same size as a pinhead.

Implantation - the fertilized egg attaches to the uterus

When the egg reaches the uterus, it sheds its shell in order to continue developing. The egg, or actually the cell lump, eventually grows firmly in the uterine wall and is enclosed by the uterine mucosa. This is called implantation. Three weeks after fertilization, the cell lump is termed an embryo which then develops into a fetus.

Hormonal changes

For the implantation to occur, the uterine mucosa must have been stimulated by the hormone progesterone that is formed in the ovary. An ovarian area called the corpus luteum produces large amounts of progesterone over a period of about 14 days. If fertilization occurs, the corpus luteum continues to produce progesterone for a few more weeks. This results in the menstruation failing and the egg being able to attach.

A few days after the egg has been fertilized, a new hormone called HCG is formed. It is the levels of the hormone that are measured to see if you are pregnant. The HCG hormone stimulates the corpus luteum to continue producing estrogen and progesterone until the placenta (placenta) is formed.

All of this helps the fetus to develop and grow.

Pregnancy Week 1

The sperm penetrates into the egg cell, which begins its journey to the uterine wall where the egg attaches. Some may have less bleeding when the egg attaches.

The child's gender and genetic inheritance are already determined. Namely, when the egg was fertilized, 23 chromosomes from the mother and 23 chromosomes from the father were mixed and laid this foundation.

Ovulation

When the egg is released from the ovary, it is captured by the fallopian tube. The egg can live in the fallopian tube for up to 48 hours.

Fertilization

The male's sperm (sperm) cells swim in large quantities (from about 500 million at first) up into the cervix, through the uterus and into the fallopian tube where the egg is waiting. Fertilization of the egg occurs approximately in the middle of the fallopian tube. The woman may also become pregnant after intercourse a few days before ovulation. Some sperm can live for up to five days after the man has had ejaculation.

The egg is surrounded by a shell that the sperms try to penetrate. As soon as a sperm manages to penetrate the shell, it becomes impervious to all other sperm. The sperm loses its tail and the head fuses with the nucleus of the egg. The egg divides into several cells repeatedly as it migrates from the fallopian tube to the uterus.

Pregnancy Week 0

The start of your last period before delivery. You do not yet know if you are pregnant, but if you are planning to become so you should already start behaving as if you were pregnant. If you have not started taking the vitamin supplement folic acid you should start now. Ideally, you should start with this a few months before the planned pregnancy and continue through pregnancy week twelve. This preventive treatment is helpful, even if you start with it first when you find out you are pregnant, and then continue to week twelve.

Folic acid prevents neural tube defects. This is a group of congenital conditions that is due to the fact that the structures around the spinal cord have not been sealed sufficiently well, and this can, for example, lead to spinal cord fractures. Folic acid you can buy prescription at the pharmacy and in most grocery stores.

If you are planning to become pregnant, you should avoid alcohol and tobacco smoking, drugs and drugs during this phase. If you are not sure whether you can take a medication you usually use during pregnancy, you should talk to your doctor.
