Early pregnancy signs

Pregnancy (medically gestation or pregnancy, from the Latin gravitas, “gravity”) described in human medicine, is the period in which a fertilized egg matures in the body of an expectant mother to become a child.

The pregnancy lasts from fertilization to birth an average of 267 days. The maturing child is usually up to the formation of the internal organs from the ninth week of pregnancy and is then known as an embryo, then as a foetus (also called foetus).  The word “pregnant” comes from the Old High German and means “clumsy” or “serious”.  The word is also used in a metaphorical sense (e.g. are pregnant with great plans).
In medicine, events that occur during pregnancy, known as prenatal (before birth), events during are perinatal and after birth are postnatal.  (All expressions are from Latin and Greek).  In other viviparous mammals pregnancy is called Eutheria.  There are many euphemisms for “pregnancy”, such as a child under her heart.

The beginning of pregnancy can be detected in various ways. In the definition of false pregnancies, there is a distinction between uncertain, probable and certain signs of pregnancy. The absence of menstrual periods, morning nausea, vomiting and signs of pregnancy are uncertain.

A pregnancy test by measuring the concentration of the “pregnancy hormone” (hCG) in blood or urine is considered probable, but not sure signs of pregnancy. To be safe, proof of a foetus is, for example by ultrasound, listening to heart sounds or the feeling of foetal movements.
