How to calculate the number of days of pregnancy if menstruation is irregular

After diagnosing the number of days of pregnancy, pregnant mothers want to know how long they have been pregnant. Indeed, the number of days of pregnancy is very important for pregnant mothers during pregnancy. However, the absence of menstruation makes it more difficult for pregnant women to calculate the number of days of pregnancy. So, how do pregnant mothers who do not have their periods calculate the number of days to pregnancy?

How to calculate the number of days of pregnancy if menstruation is prohibited

If a woman is diagnosed with pregnancy, the doctor will ask about her menstrual status, including whether her menstrual period is regular, her menstrual cycle, and her expected date of delivery. Generally speaking, the exact time of pregnancy for each pregnant woman is impossible to determine. Therefore, it is required in medicine that the expected date of delivery is calculated from the first day of the pregnant woman's last menstrual period. For women who are pregnant despite irregular menstruation, it is inconvenient to calculate the gestational period after knowing that they are pregnant, and they have already forgotten when their last period was. But you can still calculate the pregnancy time at this moment. How to calculate the pregnancy cycle of menstrual disorders?

When a pregnant woman has irregular menstruation, she simply cannot remember when her last menstruation was, so it is not reliable to calculate the time of pregnancy based on the last menstruation. Normally, the gestational age of a pregnant woman is about 38-42 weeks. In addition, the length of each woman's menstrual cycle is different, and she is also affected by menstrual disorders, so there is also a difference of one or two weeks, which may be advanced or delayed by one or two weeks.

Menstrual irregularities can be calculated based on the time of fetal movement. Normally, the fetus will move around the 18th to 20th week of pregnancy. If you don't know how many days you are pregnant, you can observe whether you have fetal movement, and determine the pregnancy period and then the delivery date based on the fetal movement.
