21 weeks of pregnancy - this is how many months? 21st week of pregnancy: sensations, development of the fetus

There comes 21 weeks of pregnancy. This is how many months? On an obstetric term-six, although my mother may well be sure that five. The difference is a few weeks, because gynecologists always round up the figure in a larger direction. It happens that a woman herself can much more accurately calculate the date of delivery, especially if she has been pregnant for a long time and led the ovulation calendar. Despite the difference in numbers, half of the time has already passed, your kid already resembles a "big doll" that perfectly hears and feels your mood and even the taste of the food that you eat. You can interact with your baby, play and understand each other.

How to determine the length of pregnancy

The exchange card says that to date,you are 21 weeks pregnant. This is how many months left before delivery? Approximately the same (slightly less) - 4.5. Some will see the baby even earlier. How to calculate the time? Usually there are two digits, very different from each other. These are the mother's own calculations, based on the dates of the last menstruation, sexual contact, calculated ovulation and own feelings. Often the calculations are correct, but doctors think differently. They take as a basis the last menstruation, so if it is logical to assume that ovulation occurred two weeks after their onset, the error will be exactly 14 days. Nevertheless, it is important for doctors to accurately determine the duration of pregnancy, so they adjust their data, based on the results of the examination on the chair, ultrasound examinations and the first movements of the fetus.

A normal pregnancy lasts 266 days, thiscounted and proven by numerous studies. This is the period from conception to the beginning of labor. It is 38 weeks, after which the child is completely ready for birth. But since few people know the exact date of conception, but take as a basis the last menstrual period, 280 days or 40 weeks go out. You are unlikely to make a mistake if you subtract 14 days from the estimated date of delivery. The calculation of pregnancy is important and necessary, but still only your baby can decide when he will be born.

What is happening now with the baby

Your baby grows and develops, but its weight nowis only 300-400 g, despite the fact that it's already 21 weeks of pregnancy. This is how many months will it take if it grows so slowly? Calm down, at this stage, the development of all organs and systems is completed, then the child will rapidly gain weight. The growth of the baby is about 25 centimeters, it has already gained half its length, now the first layer of fat will start to form. Many organs and systems at this stage are already actively involved in the work, but there are further transformations of the digestive, nervous, immune and endocrine systems.

In general, the 5th month of pregnancy endsactive development of the digestive organs. The child still receives useful substances through the umbilical cord, but already actively swallows amniotic fluid and processes them with enzymes. Thus, he receives a small amount of nutrients, and most importantly, passes the necessary training. The esophagus and stomach are getting ready for work, the intestine will keep the stools until the end of pregnancy. Only after birth will he be emptied.

Only 5 months of pregnancy, and the baby's bloodformed platelets and white blood cells, begins to work its own immune system. It's amazing how quickly the most complex neoplasms occur. The bone and muscle tissue actively grows, the teeth begin to develop in the gums. The most complex, endocrine system begins to function. Included in the work of the thyroid, pancreas, adrenal gland and pituitary gland. At this time, the spleen ripens and begins to work. The appearance of the light at this time is no longer a miscarriage, but a premature birth, while the baby can be saved and placed in an incubator.

Changes that occur in the body of the mother

There is 21 weeks of pregnancy. This is how many months - five or six? By the standards of obstetricians - the beginning of the sixth, because they all the pregnancy is divided into 280 days, 40 weeks or 10 months, 28 days each. Because of this, often misunderstandings of doctors and future parents are obtained. However, it's still a certain Rubicon, a feature that separates the first half of the pregnancy from the second. Often, women say that this week they felt like mothers. Especially this applies to those who are carrying the first baby. Now the mother clearly defines the activity time of the child, feels his movements and can communicate with him. The kid feels all the stroking of the belly very well, he also feels a voice addressed to him, songs and rhymes. Be sure to communicate with a crumb, play "in the pursuit" by fingering your stomach. It is especially wonderful when in such games the whole family, dad and older children participate.
