How many weeks pregnant can you see the embryo?

Patient's question:

No

Doctor's answer:

For normal intrauterine pregnancy, around 6-7 weeks of amenorrhea, which is more than 42 days, ultrasound should be able to detect the fetal bud and primitive cardiac. Some women have irregular menstrual cycles, delayed ovulation, and delayed implantation of the fertilized egg, which may result in a delayed fetal bud and cardiac.
