How to determine the length of pregnancy by week?
The most accurate diagnosis is ultrasound . Using a special device, you can very accurately determine the age of the fetus, using data on the size of his body. In this case, it is customary to talk about the duration of a woman's condition (calculated from the first day of the last menstruation) and the age of the baby (usually 14 days less than the duration of the gestation state). In addition, different symptoms are distinguished. In the first 14-42 days, early toxicosis can occur in the form of nausea, dizziness, fatigue. In the middle of pregnancy (18 weeks) the wiggling of the fetus may begin, although in many respects it depends on the physiology of the future mother.
Doctors establish the exact duration of the gestation period by measuring the height of the standing of the uterine fundus. This becomes possible after 10-11 weeks, when the uterus can be probed through the abdomen.
Pregnancy calendar by week
Gynecologists calculate the duration of pregnancy for weeks, helping the probing of the uterus, which increases markedly in 5-6 weeks. At 7-8 weeks, the dome protrusion of the main female organ becomes noticeable, due to which a certain asymmetry is formed. Thus, even the very first clinical examination makes it possible to assess pregnancy by weeks and term of delivery.
Ovulation also helps to answer the question at hand, if a woman knows exactly her date, or the date of conception. In the second half of the gestation period, doctors also rely on data on the circumference of the abdomen of the future mother, as well as on the length of the baby.
Thus, there are many ways to know when a baby is born, or when it was conceived. It is important to know that the informativeness of any of the above methods depends on the doctor's experience, the date of measurement of a particular parameter, and also on the physiology of a woman or a baby.
