Is it possible to determine in advance the day of childbirth
One of the most exciting questions during pregnancy is the question of determining the expected date of birth of a child. A single-valued answer to it no one will ever give, since too many factors determine it. Neither a woman nor a doctor can tell the exact time of fertilization, which depends on the individual physiological characteristics of the female and male body. The males are:
1) sperm motility;
2) their fertilizing ability;
3) the time of viability in the body of a woman.
Female:
1) the time of ovulation - the release of the ovum from the ovaries and its readiness for fertilization;
2) the continued viability of the oocyte after ovulation;
3) the duration of the menstrual cycle.
Since the release of the egg from the ovaries can occur between the 8th and 16th days of the cycle, if we take into account approximately two days, during which the spermatozoa can retain their properties for fertilization, it can be assumed that pregnancy occurs between the 8th and 16th days of the cycle,m and 18th days of the menstrual cycle. The cycle is considered from the first day of one month to the first day of the next. External factors, such as lifestyle, nutrition, stress effects, are also taken into account. Therefore, to calculate the time of delivery becomes even more difficult. The average duration of gestation is 40 weeks, fluctuations within 2 weeks are possible, i.e. births may occur within
38-42 weeks. Using as many methods as possible to determine the time of delivery, you increase the chances of knowing their exact date.Option 1. The most common and convenient for a woman. By the first day of the last menstruation 280 days or 40 weeks are added, because during critical days a woman can become pregnant. It can be considered easier. From the first day of the last menstruation, subtract 3 months and add 7 days to the received date, and get the possible date of birth.
Option 2. By the time your child moves for the first time. For women who are preparing to become a mother for the first time, by the date when the child first started to move( this happens on the 20th week), it is necessary to add another 20 weeks. For re-relatives who are familiar with the sensation of the first shock and recognize it already at the 18th week, it is recommended to add 22 weeks.
Option 3. By the term of pregnancy established in the women's consultation at your first visit. By the way, the earlier a woman turns to a doctor( this is better done in the first 12 weeks), the less will be the error in the term of pregnancy and, accordingly, in the time of delivery.
Variant 4. Based on data obtained as a result of ultrasound. At the first admission in a woman's consultation to a woman who applied for a delay in menstrual and suspicion of pregnancy, the doctor should do an ultrasound. Examination can be carried out using a sensor, passing them on the stomach or through the vagina. This method allows you to estimate the size of the fetus, which in the first three months of pregnancy is increased by 0.7 cm per day, and if there are abnormalities in its development, it is timely to identify them. Ultrasound is the most reliable, safe and affordable way to assess the condition of the fetus. Based on the data obtained with this method, intra-uterine operations are currently performed to cure an unborn baby. In a normal pregnancy, ultrasound is performed three times:
1) when you first visit the doctor;
2) at 16-18 weeks to determine the compliance of fetal development with the term of pregnancy;
3) at the time of 32-35 weeks to determine the position and weight of the fetus, the state of the child's place.
You will be more confident in yourself and quietly expect the forthcoming birth of your little man, if you know that your child feels well.
Variant 5. For the future mother it is important to know that the antenatal holiday begins with 30 weeks. This is the time when you can prepare for the upcoming appearance of the child.
All these methods will help to establish the long-awaited date. But learn to trust your own body, because your baby, regardless of the calculations, will choose the decisive moment when he wants to see you.
