It is not too late to have a second child at the age of 36. A woman’s ovaries function better before the age of 40 and generally do not show decline. If a woman’s ovaries function normally at the age of 36 when she has a second child, the follicles develop better, so the patient is not too old to get pregnant. However, if a woman gets pregnant over 35 years old, she is of advanced maternal age, and the patient will have a higher risk of embryonic arrest, preterm delivery, gestational diabetes, hypertension, and various other risks after pregnancy. Therefore, patients must go to the hospital for maternity checkups in a timely manner after pregnancy, and non-invasive genetic tests and amniocentesis should be done to screen the intelligence of the fetus, and ordinary Down’s syndrome screening should not be done, because the results of the test are not accurate when Down’s syndrome screening is done. As long as the patient has no problems during the screening process throughout the pregnancy, the delivery is usually normal.
