Menstruation plays a crucial role in women, and many women experience menstrual irregularities. Mild menstrual irregularities do not affect conception. After pregnancy, women can calculate the due date based on their last menstrual period to understand the time when the fetus will meet their mother. So, how to calculate the due date for abnormal menstruation?

Irregular menstruation in women is a common symptom in daily life, and there are various methods to estimate the due date. Generally, women will experience pregnancy reactions around 42 days of pregnancy, and based on these reactions, the expected delivery date can be calculated. It can also be observed through ultrasound examination. Generally, the size of fetal development does not differ from the actual conception time by one or two weeks.
For women with regular menstrual cycles, the estimated due date can be calculated based on their last menstrual period, which is around 40 weeks or 280 days. Of course, the estimated delivery date is not very accurate. Each woman's physical condition is different, and the delivery time may also be different. Delaying or advancing the delivery time usually does not exceed half a month, which is considered normal. According to the estimated due date, you can prepare the items for delivery, prepare to go to the hospital for delivery, and choose the delivery method based on the specific situation.
Women should not overeat during pregnancy. Although it can supplement the nutrition of the fetus, overeating can cause the fetus to become too large, and the estimated delivery date may not be accurate. In addition, it can also cause some difficulties during delivery. During pregnancy, it is recommended to eat nutritious foods such as apples, eggs, milk, and lean meat, which not only ensure the nutrition of the fetus but also prevent it from becoming too large.
