3rd Week of Pregnancy

This happened in the 3rd week of pregnancy for MOM & baby...

Now here we go: the real pregnancy starts finally in the 3rd week, because now the egg is fertilized.

If unprotected sex during the fertile days took place, a good chance that the sperm of the husband in the fallopian tube to meet sent out egg at ovulation and the best candidate is passed through the protective cover of the much larger egg.

Usually have sperm high struggled himself up into the fallopian tubes, rarely fertilization takes place when the egg is hiked up in the uterus.

The baby in the 3rd week

Immediately after a sperm to fertilize the egg, in the 3rd week of pregnancy has managed numerous processes underway, whose Endergebnis is a new person contact: the outer shell of the egg changed its structure and allows no other sperm. Blend the cores of both cells (sperm and egg) and the “new” cell begins to divide.

On the second day, the cell collection consists of four on the third day out of eight cells. Scientists call derived from the Latin word for Mulberry him now “morula”, because the embryo (as the later baby is called now) resembles exactly that.

About results on the fourth day a cavity inside the morula – and then, again, it gets a new name: “germ bubble (blastocyst).The germ bubble consists of “Layer” and the “trophoblast”. The embryo arises from the layer of the trophoblast of placenta (placenta). Via the placenta and the umbilical cord related, the baby is later supplied with oxygen and nutrients and waste products of metabolism are derived.

The fertilized egg moves tirelessly throughout this period – at about the end of the 3rd week, it reaches the uterus. It now consists of 70 to 100 cells and “Embryo” is now called. At the beginning of the 4th week of the embryo in the womb settles.

The mother in the 3rd week

In the 3rd week the most pregnant women do not yet know that they are pregnant – there is also no evidence. Pregnancy symptoms occur later at http://www.shopareview.com/, but there are women who have been a clue. Because some women experience implantation: If the egg drills at the end of the 3rd week of pregnancy in the lining of the uterus, to anchor himself as deeply and firmly, can that hurt tiny vessels and cause a slight bleeding, implantation bleeding. Many women feel the implantation as a slight stinging and evaluate the bleeding as spotting or early menstrual period.

Still, The hormonal changes, ovulation and fertilization in motion are used and prepare the expectant mother’s body for the next 38 weeks, expire once completely to notice this.

It is the first official act of the hormones to prepare the uterus for the arrival and implantation of the fertilized egg. Because only, if the egg really settles, the baby can be supplied sufficiently with the necessary nutrients and oxygen. The so-called “Eizellbläschen”, which served as a protective case for the egg until the ovulation is responsible for this operation. After ovulation, it is given a new name and produced as a corpus luteum the hormone progesterone, which in turn ensures that the lining of the uterus is built up. A well-designed and perfused endometrium is the best prerequisite for a successful implantation.
