How is the number of weeks of pregnancy calculated?

Patient's question:

No

Doctor's answer:

Hello, in this case, the pregnancy duration is calculated from the first day of your last menstrual period. Generally, 7 days make a week, and you can estimate the gestational week based on the date of your last menstrual period. During the early stages of pregnancy, it's important to strengthen nutrition, undergo regular prenatal check-ups, and avoid sexual activity.
