Doctor's answer:

Hello, under regular menstruation, the time of pregnancy is calculated from the first day of the last menstrual period. That is to say, you are currently about 37 days pregnant. It is recommended to keep a relaxed mood and avoid tension and anxiety. It is suggested that:
1. Maintain a reasonable diet according to personal taste.
2. Abstain from sexual activity during the first three months of pregnancy.
3. Regularly undergo prenatal check-ups.
