Sometimes when calculating the period of pregnancy can help date of conception, if known more or less accurately.


Which way is more precise

5
To reliably calculate the date of birth by using ultrasound. It is important that the first study was conducted in the early stages of pregnancy up to 12 weeks. Ultrasonography conducted at the later stages of pregnancy, gives less reliable information about the date of birth, as this method of determining pregnancy based on the measurement of the size of the fetus, and the growth and development of the fetus during pregnancy is strictly individual.
6
To calculate the estimated date of childbirth possible, using the date of care tothe birthOh a vacation. It is calculated by the 30th week of pregnancy. Means to determine the date of birth should be added to the start date of decree 10 weeks.

Advice 3 : How to determine the time of birth of the child

The gynecologist can establish the period of pregnancy during the measurement of the size of the uterus — determination of the level or height of standing of bottom of uterus, circumference of the abdomen. For a period of 4 weeks of pregnancy the uterus is about the size of a chicken egg in 8 weeks — with a goose egg. At 12 weeks the uterus is increased to the size of a male fist, the bottom of the uterus extends to the upper edge of the pubic bone. At 16 weeks of pregnancy the fundus midway between the womb and the navel, and at 24 weeks it is at the level of the navel. The largest size uterus gets to 36 weeks (abdominal circumference up to 90 cm), by this time the bottom of the uterus rises to the ribs, and then 40 weeks lowered a couple of inches. Lowering of the uterus means that the baby is preparing to leave.

Advice 4 : How to know the exact day of conception

Conception is the process of merging the female and male germ cells. Sperm retain their ability to fertilize the egg within 2 days. And if female reproductive cell will enter the stage of ovulation, then chances of pregnancy. If in this period, ovulation is absent, the conception will not occur.
How to know the exact day of conception
You will need
  • - a thermometer;
  • - notebook and pen;
  • - analysis of mucus from the cervix;
  • - pregnancy test;
  • - the results of the ultrasound.
Instruction
1
To calculate the day of conception of the child, use the special calculators available on the Internet.
2
Since the most favorable time for conception of the child is the date when ovulation occurs, the exact time of conception will coincide with the ovulation date. For the duration of the menstrual cycle is 28 days ovulation occurs on 14 th day. The probability of pregnancy this day the most high. When the length of cycle in a 21 - 24 day phase ovulation occurs 10 to 12 a day, with a cycle in 32 to 35 days –ovulation - 16 – 18 day.
3
Calculate the date of conception (ovulation) with the help of the graph of basal temperature. When measuring basal temperature every morning, the thermometer introduced into the rectum (about 5 cm) for 7 – 10 minutes. If the temperature is less than 37 degrees, then the female body is prior to ovulation if the temperature exceeds 37 degrees, that is after ovulation. Date before the increase in basal temperature – ovulation stage.
4
A few days before the maturation of the egg is sticky and thick vaginal discharge becomes transparent and sticky. During this period a very high probability of conception of the child.
5
In the middle phase of the menstrual cycle to consult a specialist – a gynecologist. He will take on the analysis of mucus from the cervix and determine the date of ovulation (conception) with an accuracy of 1 – 2 days.
6
Purchase in a drugstore the test for determining ovulation.
7
Contact the experts conducting the ultrasound examination. This is the easiest and most reliable way to determine the exact date of conception.
Note
