High-risk pregnancy ages are generally considered under 20 and, more significantly, over 35, with increased risks for both mother and baby as age rises. For those over 35, risks include gestational diabetes, high blood pressure, miscarriage, premature birth, chromosomal issues like Down syndrome, and a higher likelihood of needing a C-section. Younger mothers (under 20) also face elevated risks, often related to socio-economic factors and overall health.
At 37, many women successfully conceive, but fertility can decline with age, and IVF may be necessary again. It's important to discuss your specific situation with a fertility specialist who can provide personalized guidance based on your health and history.
Pregnant patients younger than 30 have about a 12% risk of miscarriage. There's a slight increase in risk between ages 30-34, but the risk rises higher for patients ages 40 and older. Patients who are age 45 or older have an estimated 93% risk of miscarriage.
Risk is higher for women younger than 17 or older than 35. Medical history. Previous miscarriages, a family or fetal genetic condition, or a prior C-section can all cause a pregnancy to be considered high-risk.
A woman's peak reproductive years are between the late teens and late 20s. By age 30, fertility (the ability to get pregnant) starts to decline. This decline happens faster once you reach your mid-30s. By 45, fertility has declined so much that getting pregnant naturally is unlikely.
High-Risk Pregnancy Signs & Symptoms
You may be considered high-risk if you have a history of miscarriage, preterm labor, or cesarean delivery. Likewise, if you've already had one child with a birth defect, any subsequent pregnancies may be treated as high-risk.
Factors Considered For High Risk Pregnancy
Difficult pregnancies in the past. Chronic medical conditions such as diabetes, high blood pressure or thyroid disorders. Family history of genetic conditions. Rh incompatibility.
Most miscarriages happen in the first 12 weeks of pregnancy (known as early miscarriage). It is estimated that early miscarriages happen to 10-20 in 100 (10 to 20%) of pregnancies. It is estimated that second trimester loss (late miscarriage) happens to 3-4 in 100 (3 to 4%) of pregnancies.
Most pregnancies after the age of 35 are healthy and successful. But it's good to know about the potential complications with advanced maternal age pregnancies. Talk to your pregnancy care provider about what genetic screening tests they recommend or what you can do to stay healthy.
At 20 weeks of pregnancy, a female fetus has 6–7 million of eggs. By the time the woman is 30 years, she will have lost nearly 90% of her eggs and at the age of 40 years, only around 3% of eggs are left. Most women are no longer able to become naturally pregnant in their mid-40s.
Down syndrome occurs in people of all races and economic levels. The risk increases with the mother's age (1 in 1250 for a 25 year old mother to 1 in 1000 at age 31, 1 in 400 at age 35, and about 1 in 100 at age 40).
Your age affects the health of your eggs. Women reach the peak of their fertility at around age 24. After this age, egg quality slowly deteriorates until around age 37, and then deteriorates more rapidly until about age 42. After roughly age 42, fertility for most women basically falls off a cliff.
A woman's most fertile years are between her late teens and late 20s. By around age 30, fertility starts to slowly decline and by mid-30s the decline speeds up. But the decrease in chance of pregnancy after age 35 is gradual and more like a slope than a cliff, at least until age 40.
Make healthy choices
You can reduce your risk of pregnancy complications by: Avoiding beverages containing alcohol and any nonprescription drugs or medications. Identifying potential health risks before getting pregnant. Tell your provider about your familial and personal medical history.
Under the PWFA, an employer must accommodate a worker's known limitation related to pregnancy, childbirth, or related medical conditions, absent undue hardship.
A high-risk pregnancy is one in which a woman and her fetus face a higher-than-normal chance of experiencing problems. These risks may be due to factors in the pregnancy itself, or they may stem from preexisting maternal medical conditions, such as cancer, diabetes, or lupus.
A fever is especially worrisome if you also have:
The "3-2-1 Rule" in pregnancy is a guideline for first-time mothers to know when to call their midwife or doctor for active labor: consistent contractions every 3 minutes, lasting 2 minutes each (or 1 minute long for some variations), for over 1 hour. It helps differentiate true labor from false labor (Braxton Hicks), signaling it's time to head to the birthing center, while subsequent pregnancies often follow the faster 5-1-1 rule.
Generally speaking, getting at least two ultrasounds during a normal pregnancy is recommended. Both happen during pregnancy. However, the first comes early, while the second is given in the second trimester.
First and foremost, don't smoke tobacco products during pregnancy. Smoking increases the risk of health problems for babies such as preterm birth, low birth weight, and birth defects. It may also increase the risk of miscarriage or sudden infant death syndrome.
Research has previously shown that at 8 weeks, the chances of having a live pregnancy is 92%, increasing to 97% at 12 weeks gestation. However, obstetricians have reported that there are no actual clinical guidelines as to when a woman should or should not announce her pregnancy.
While delivering at age 35 and older is officially considered “advanced maternal age,” Dr. Kalish notes that in reality, there's no “magic number” for being at-risk for complications. “A healthy 38-year-old could have an easier pregnancy than a 20-year-old who has multiple medical issues,” Dr. Kalish says.
