When registering a woman for pregnancy and childbirth in an antenatal clinic, the main task of a gynecologist is to accurately determine the day of pregnancy. This is very important in order to correctly and efficiently monitor the patient's pregnancy. There are several ways to determine the day of pregnancy in a woman.
Instructions
Step 1
Determination of the day of pregnancy by ovulation and date of conception. Ovulation is the period of the menstrual cycle when the child is conceived. It usually occurs in a woman in the middle of her menstrual cycle. If a woman's menstrual cycle is 28 days, then ovulation can occur on day 14. That is, the day of pregnancy can be considered the day of ovulation in a woman.
Step 2
Determination of the day of pregnancy by the date of the last menstruation. This method, as a rule, is designed to determine the day of birth, and not the day of pregnancy, but the second can also be easily determined by it. It is necessary to subtract three months from the first day of the last menstruation and add seven days. Based on the received date of the expected birth, you can also calculate the day of pregnancy.
Step 3
Determination of the day of pregnancy by a gynecological examination. An experienced gynecologist, upon examination, can accurately determine the day of pregnancy, based on the size of the uterus, if the gestational age does not exceed 12 weeks.
Step 4
Determination of the day of pregnancy on the basis of ultrasound. The accuracy of this method depends on the duration of pregnancy. The longer the period, the more difficult it is to establish the date of conception of the child.
Step 5
Determining the day of pregnancy by the first movement. As a rule, in women who give birth for the first time, the baby begins to move at 20 weeks of pregnancy. In multiparous - at 18 weeks. Gynecologists advise a woman to remember the first intrauterine movements of her child and enter these data into the birth chart.
Step 6
Determining the day of pregnancy by measuring the length of the uterus. Everything is simple here. The gynecologist measures the length of the uterus with a measuring tape. As a rule, its length is equal to the gestational age. For example, if the length of a woman's uterus is 33 centimeters, then the gestational age is 33 weeks.
