I am three months pregnant, do I need to have a prenatal examination? And do I need to register?

Three months pregnant.

Doctor's answer:

Hello, if you are three months pregnant and have not had a check-up yet, it is necessary to go to the hospital for prenatal examination promptly. You can now have a color Doppler ultrasound examination to check the development of the fetus.

It is necessary to register, and in some places, you may also need a birth certificate. It is important to register early. Pay attention to adjusting your emotions and undergo regular prenatal examinations. Do you understand?
