How many weeks does pregnancy actually last? The pregnancy calculator helps you estimate your due date and pregnancy age, calculated from the time of your last menstrual period.
How many weeks is pregnancy? Pregnancy calculator
Pregnancy calculator, i.e. Naegele’s method, does not provide the actual age of the fetus or the date of delivery, only the approximate age of pregnancy and the expected date of delivery (PTP). This is because the exact moment of conception from which the actual age of pregnancy should be counted is very difficult to determine. Moreover, the pregnancy calculator assumes a woman’s regular cycles that last 28 days, 30-day months, and exactly 40-week pregnancy duration. These rigid numbers, and the realization that each baby grows at a different rate, explain why only a few percent of all deliveries are scheduled for this method.
Are you pregnant or breastfeeding? Check prenatal vitamins that will help you maintain the proper level of vitamins and minerals in your body. After consulting your attending physician, you can include, for example, Doppelherz aktiv Mama PREMIUM in your diet.
- Check what tests you should do during pregnancy
Nevertheless, scheduling a due date and calculating the age of pregnancy is very important, especially in abnormal pregnancies. Knowing the due date and age of pregnancy using the pregnancy calculator allows you to plan examinations, predict what will happen in a given month and at least theoretically prepare parents for adopting a child into the world. In the case of, for example, premature births, thanks to the knowledge of the age of pregnancy, doctors can be prepared to help a premature baby quickly and accurately.
When in doubt about pregnancy and health issues, seek advice from an online gynecologist. The TV visit gives you the opportunity to take advantage of consultations without visiting the clinic. This is especially useful in situations where a personal meeting with the doctor is not necessary.
How many weeks does pregnancy actually last?
How many weeks does pregnancy actually last? Is it the said 40 weeks? In fact, pregnancy lasts about 38 weeks, or about 266 days, from the time the egg is fertilized until the baby is born. For practical reasons and for the possibility of using the pregnancy calculator, this period is defined as 40 weeks (counting from the beginning of the last menstruation), i.e. 280 days.
- Do you know what prenatal testing is? See for yourself
You’re pregnant? Are you planning a baby? Check the body’s absorption of folic acid to exclude the presence of a gene mutation that affects its absorption. The daily dose of folic acid can be provided by the dietary supplement Folian Quatrefolic.
Calculating the age of pregnancy and due date based on ultrasound examination
The ultrasound examination, carried out up to the 10th week of pregnancy, is of much greater value in determining the due date than the Naegele method described above. The doctor who performs the test measures the pregnancy vesicle, checks the size of the baby and on the basis of these data determines the age of the fetus and gives the approximate date of delivery. The test is the more reliable the sooner it is performed. Thus, the later the first ultrasound examination is performed, the more error-prone the result is.
In order to determine the age of pregnancy and the date of delivery, sign up for a pregnancy ultrasound, which is the basis of mother’s and child’s health prophylaxis. After booking the service, it is enough to go to the examination on the specified date.
If you are pregnant, you need to maintain adequate levels of nutrients. We recommend, for example, Prenatal Multivitamin – a complex of vitamins and minerals for pregnant women Terranova. You can also reach for the Daily Mum ° for pregnant women, a dietary supplement that can be modified depending on your needs and expectations.
Other ways to determine the age of pregnancy and due date
It also happens that a woman comes to a doctor already in advanced pregnancy, without knowing the date of the last menstruation or the date of conception. Then the age of pregnancy and the date of delivery are determined on the basis of such information as the moment of feeling the first movements of the fetus (the elements feel them around 19-20 weeks of pregnancy, multiparous ones around 17-18 weeks) and the height of the pelvic floor (the higher the pelvic floor, the more advanced pregnancy).
If you are planning a pregnancy, it is worth performing HLA-C genotyping – a mail-order test available on Medonet Market for the diagnosis of the causes of habitual miscarriages.
It is worth emphasizing that the methods of determining the age of pregnancy and the date of delivery determined on the basis of the child’s sensation of movements and the position of the uterine floor give very approximate results and are subject to a large error. In particular, these results may be imprecise when the woman is very thin, extremely obese, during multiple pregnancies, and in the presence of polyhydramnios and uterine tumors.
When preparing for pregnancy, it is worth carrying out appropriate tests that will help maintain good health for the future mother and baby. You can buy a blood test package on Medonet Market. In addition, it is worth taking care of the appropriate level of folic acid in the body, which supports the proper development of the child and reduces the risk of miscarriage. The Swanson brand offers hypoallergenic folic acid, safe for allergy sufferers.
