The spermatozoon has to join an ovule in order to conceive a baby. The union of these two cells forms an egg, in other words, the first cell of the baby. At this moment a new being is born.
The ovule is impregnated two weeks before the expected date of the menstruation. Three weeks after conception, the baby’s heart is already beating inside the mother’s uterus. In this period, many women do not yet suspect that they are pregnant because the menstruation delayed one week only.
The baby grows day after day during 40 weeks, the time that pregnancy usually takes. During pregnancy the woman needs to be more careful with her health and nutrition.
