A woman who gives birth at age 28 is not considered to be in advanced maternal age. 25-35 years is the peak of childbearing and 28 years is a better time to conceive. Advanced maternal age refers to women who are expected to give birth at age 35 or older, or who are 34 or older at the time of conception. Although women who give birth at the age of 28 are not considered to be of advanced maternal age, they should still undergo pregnancy checkups as prescribed by their doctors, including progesterone and HCG tests in the early stages, ultrasound at 11-14 weeks to observe the development of the fetus. In addition, the mother should monitor her blood sugar, blood pressure and blood lipids throughout the pregnancy to ensure the health of the mother and the fetus.
