It is unclear why people say that pregnancy lasts 9 months, but in fact - 40 weeks. If it lasted a little less, it should be considered premature. Of course, it is impossible to determine with certainty the exact date of birth. Of course, you can calculate the preliminary date of birth quite accurately, but not the fact that it will be true. Almost no one, even doctors, can say with certainty how many days the pregnancy of your body lasts, and how many births will take. There is no single answer to the question of how many weeks pregnant women go, since this period depends on a huge number of factors. Even if you know exactly when the conception occurred, you won’t be able to find out how fast the sperm was, how long it was implanted in the egg, how long it moved through the fallopian tubes, how long the fetus will develop in the womb. It all depends on the individual characteristics of the body. However, there is still a small pattern of how long the pregnancy lasts most often, and when the baby is ready to be born. One can only rely on these calculations, but not rely on one hundred percent. Certain estimates have shown that pregnancy ends at 37-42 weeks. In the event that it is 43 weeks, childbirth is caused artificially so that there are no problems with the placenta and the baby’s breathing.
So, how long does a pregnancy last, according to the midwives? In most cases, women have 38 weeks from the moment of fertilization to the start of delivery, which is 266 in terms of days. However, most often women do not know the exact moment of fertilization. But, most likely, they perfectly remember the date of the last menstruation. It is she who is taken for the basis of calculation. Gynecologists claim that on average 280 days pass from the first day of menstruation to childbirth. Most likely, the actual gestational age is two weeks less than the so-called menstrual period.
If you count the number of days, you can see that the period is exactly nine months, as people used to say. The average cycle lasts about 28 days, it is standard for most women. That is why a period of 40 weeks is calculated mainly for a cycle of 28 days.
Many other factors will influence how long a pregnancy lasts: first of all, the health status of the expectant mother will have an important impact. Depending on the lifestyle a woman led, the rate of development of the fetus, its condition, and psychological background will depend. It also happened when a woman gave birth on a day set for herself personally, for example, on a holiday, or on the return of her husband from a long business trip. However, the psychological attitude is not always decisive. A huge influence on how long the pregnancy lasts is exerted by such a factor as heredity. If your mother gave birth to you before the due date, it is likely that you will have the same. Almost all calculations are conditional, and trying to conceive a baby in order to give birth on New Year's Eve is impossible. If at the end of the term you have some doubts about whether you have not transferred the child, you should pay attention to your well-being and the behavior of the baby.
In any case, doctors carefully monitor the pregnancy and you need to follow all the recommendations. It is difficult to disagree with the fact that no matter how long or hard the pregnancy lasted, this period is truly magical! No need to worry about nothing, you just need to enjoy your condition, because it will end pretty soon. It remains only to wish the baby a light birth and health!
