How to calculate pregnancy week if menstruation is irregular

If a woman becomes pregnant, the doctor will generally ask her about her menstrual period, because this will help them better infer how long the baby has been in her body. However, some women have irregular menstruation, which causes them to not remember the time of their menstruation clearly. So how should we calculate the pregnancy cycle time if the menstrual period is irregular?

1. How to calculate gestational age if menstruation is irregular

If you have irregular menstruation and cannot remember the date of your last menstrual period, you can ask your doctor to estimate the date based on the time when early pregnancy reactions began, the time when fetal movements began, the height of the uterine fundus measured by hand, and the length of the uterus measured by a ruler.

2. How to calculate the gestational age according to menstruation

If you are lucky enough to have your period every 28-30 days, most doctors will calculate the gestational age based on your last menstrual period, which is usually accurate. According to medical regulations, the expected date of delivery is calculated from the first day of the last menstrual period, and the entire pregnancy period is 280 days, or 10 months of gestation. The calculation method is to start from the first day of the last menstrual period, subtract 3 or add 9 to the month, and add 7 to the day. For example, if the first day of the last menstrual period is April 21, 2000 in the Gregorian calendar, the expected date of delivery should be January 28, 2001. If you only remember the first day of your last menstrual period on the lunar calendar, you should convert it to the solar calendar and then calculate the expected date of delivery. Pregnant women give birth between 38 and 42 weeks of gestation, which is considered full-term. Since the length of each woman's menstrual cycle is different, it is normal for the estimated due date to differ from the actual due date by 1 to 2 weeks.

3. How to regulate irregular menstrual cycle

1. Learn to relieve stress: Usually due to high work pressure, people strive to do better at work, which affects menstrual irregularities. In a situation like this, you need to adjust your mindset appropriately, relax, and combine work and rest. For example, you can go hiking, singing karaoke, shopping, etc. on weekends to relieve fatigue from the week and relax your body and mind.

2. Don’t stay up late : Have a regular life, go to bed early and get up early, don’t stay up late, have breakfast, lunch and dinner on time every day, don’t eat supper after 10 o’clock, and adjust your body to avoid irregular menstruation.

3. Soak your feet in hot water : As the saying goes, "Cold starts from the feet." Pay attention to keeping the lower body warm. Too much cold in the body can also cause irregular menstruation. Soaking your feet in hot water before going to bed every day can both expel the cold in the body and promote sleep.
