If you are newly pregnant and don't know, does the pre-marital examination affect it?

Patient's question:

No

Doctor's answer:

Hello, if it's just an ultrasound, the radiation is relatively small and there's no need to worry, because ultrasounds are also required for prenatal examinations in the future.
It is recommended to wait for a month and then go to the hospital for a check-up to see the development of the fetus.
