6. SSW (Pregnancy & shy; week)
In the sixth week of pregnancy (SSW) the embryo is about four millimeters long. At the latest this week, the heart begins to beat. Pregnancy symptoms such as fatigue and morning sickness can occur at this time for the first time or to increase.
In addition to the physical problems that may occur, especially in the first trimester of pregnancy, many pregnant women also suffer from psychological effects of hormonal changes. Do not worry: Also this time is usually passed over the first three months.
Proper nutrition during pregnancy is now particularly important because the hormonal changes weakens the immune system and makes you more susceptible to infection, the text of which can affect the unborn baby also. Also make especially in the first weeks of pregnancy in addition to a folic acid-containing diet one folic acid-a preparation (from the pharmacy)! a dose is recommended by 0.4 milligrams daily during the first three months of pregnancy. From the 4th month of pregnancy supplemental folic acid has no effect on children's development, but it can have a positive effect on your body.
Once the pregnancy is known, carried the initial examination the gynecologist, in which also the mother pass is handed out. then follow Checkups at intervals of four weeks up to 32 weeks. From 32 weeks until the expected date of delivery, this distance is reduced to two weeks. If the calculated date exceeded, by the 10th day every other day, controlled by 14 days daily. are furthermore three large checkups with ultrasound intended:
During pregnancy, the body of the mother of many is hormones flooded. The interaction of these intercellular signaling substances makes sure to provide the body to mother and baby.
Especially in the first three months of pregnancy, as well as the sixth Schwangerschaftswohe (SSW), raises the body one to the new situation. by progesterone-Distribution will relax the uterine muscle, so the baby can grow undisturbed, the uterus is softer. The gynecologist can now also palpate that the cervix is fixed and immovable, one of the first palpable pregnancy signs.
The pregnancy hormone HCG (Human chorionic gonadotropin) is suppressed and prevents re-ovulation, menstruation. From about the third month takes over the placental hormone HPL (Human placental lactogen) these tasks. estrogen stimulates the flow of milk for the baby after birth through breast milk can be fed. And also for the birth of the body by the hormone takes care of things, relaxin forms. This hormone makes the tissue around the area of the pelvic floor and the cervix more elastic.

Ultrasound can watch the pulse of the blood vessels.
Neck and head already exist in the sixth SSW - ultrasound are at the head of the Equipment for eyes, ears and brain to recognize. Now also the back strand further develops itself to the spine and compared to the rest of the body is particularly large developed. Of the backliner extends from the neck down to the point where the wing-like systems created for the legs, and not end at this stage in a tail, a remnant from the evolution of the later forms again. The embryo develops from top to bottom, so that the head compared to the rest of the body appears oversized large.
From a part of embryonic tissue, the middle germ, a large number of so-called produced at this time skeleton buds. From them gradually form 33 or 34 whirl. Below the neck vertebrae 12 thoracic vertebrae emerging from which the arc-shaped ribs grow. In this way, forms of thorax. Between the vertebrae, a gap in which later bundle of nerves from the spinal cord are created.
