1 Definition

The period during which a fertilized ovum grows in the body of a woman to become a child is called pregnancy. On average, the duration of a pregnancy (from the fertilization to birth) is 267 days. The last menstruation is approximately 14 days before insemination, though the pregnancy is calculated from this date and therefore lasts 40 weeks (10 months).

2 Course of a pregnancy

  • Six days after insemination, the fertilized ovum finds a place in the uterus.
  • From approximately the 5th week onwards, the pregnancy can be verified by simple tests (urine samples). The heart begins to beat. Most women feel weak during the initial months due to the change in hormones. Many vomit frequently, feel unwell and like to sleep a lot.
  • From the 7th week onwards, the embryo reacts to stimuli from outside.
  • In the 4th month, the development of organs is completed and the fetus begins to grow.
  • In the 5th month, the mother can feel the first movements. The fetus is able to taste and reacts to cold, pain, pressure and sound.
  • In the 6th month, the lungs are already developed.
  • In the 7th month, the fetus doubles its weight and then weighs approximately 1 kg and measures 34 cm. During the last months of pregnancy, the woman often faces physical problems. The child weighs 3 to 20 kg with amniotic fluid and uterus.
  • In the 10th month, the baby is born. It then weighs on average approximately 3.4 kg.
