Can you do a transvaginal ultrasound at 4 weeks pregnant?

Patient's question:

No

Doctor's answer:

Hello, generally, an early pregnancy test can be done around day 35 of a missed period, or a blood HCG test can be taken 10 days after intercourse to confirm pregnancy. After pregnancy, it is important to rest and maintain proper nutrition, avoid spicy and irritating foods, and regularly undergo prenatal examinations such as ultrasound for anomaly screening and Down syndrome screening.
