Early pregnancy carries lower conception rates and higher risks of chromosomal abnormalities. Regardless of whether it's a first pregnancy or subsequent births, women aged 35 or older at full-term delivery are medically classified as advanced maternal age. Female age significantly impacts ovarian and egg quality. As women age, eggs gradually deteriorate and ovarian function declines, reducing fertility rates.Even if pregnancy occurs, the risks of miscarriage and fetal abnormalities are elevated.
Due to factors like ovarian function decline and egg aging, older women face increased chances of anembryonic pregnancy during early gestation, leading to higher rates of infertility and early miscarriage. Additionally, the probability of chromosomal abnormalities rises during the initial stages of embryonic cell division.
Strategies for Coping: Adjusting Mindset and Lifestyle
Accept the reality of higher pregnancy risks, prepare mentally, and strive to maintain emotional calm.
Attend regular prenatal checkups, maintain a consistent daily routine and balanced diet, and avoid staying up late or overexerting yourself.
Tips: Managing Pregnancy Weight
Mothers-to-be of advanced maternal age should pay special attention to weight management during pregnancy. Alongside dietary control, appropriate exercise is recommended—but only after the pregnancy is stable. Engaging in 30 minutes of exercise three times per week can effectively boost metabolism, enhance stamina, and aid both delivery and postpartum recovery.
What is the ideal weight gain range during pregnancy? This depends on the mother's pre-pregnancy BMI. For mothers with a normal pre-pregnancy BMI, weight gain should be controlled between 11–13 kilograms. Mothers with a significantly high pre-pregnancy BMI should pay special attention to weight gain during pregnancy.
Mom's Question: Should I take extra progesterone supplements during early pregnancy?
Doctor's Answer:
Progesterone helps stabilize the fetus, but it's primarily a treatment medication, not a preventative one. This means when a pregnant woman shows signs of threatened miscarriage, the doctor may prescribe progesterone to stabilize the uterine lining and ensure the embryo implants securely.Bleeding during early pregnancy—regardless of volume or color (bright red or brown)—should be considered a potential sign of threatened miscarriage and requires medical evaluation. However, if the expectant mother's condition is stable, progesterone supplementation is unnecessary for preventing a miscarriage that may not occur.
Mid-Pregnancy Risks: Placenta Previa, Hypertension, Hyperglycemia
Chromosomal abnormalities are congenital disorders. For example, Down syndrome results from an extra copy of chromosome 21, leading to intellectual or structural abnormalities in the fetus. Expectant mothers can confirm fetal health through chromosomal screening tests, such as early pregnancy chorionic villus sampling (CVS) or mid-pregnancy maternal blood screening for Down syndrome.
Additionally, older pregnant women are at higher risk for placenta previa, gestational hypertension, and gestational diabetes. Regular monitoring through ultrasound scans, blood pressure checks, urine protein tests, and gestational diabetes screening is essential to assess maternal health. These tests are included in routine prenatal care, and expectant mothers must attend all scheduled appointments.
