Doctor's answer:

Hello, the month of pregnancy refers to the last menstrual period according to the lunar calendar, and in your case, the last menstrual period was on February 21 of the lunar calendar, which means that day. Generally, in clinical practice, the duration of pregnancy and the estimated due date are calculated from the first day of your last menstrual period. It is recommended that you maintain a relaxed mood during pregnancy, pay attention to adequate rest, focus on strengthening nutrition, and regularly undergo prenatal examinations.
