Pregnancy Over 35 (Advanced Maternal Age)
The short answer
While pregnancy after 35 carries some increased risks (including chromosomal abnormalities, gestational diabetes, and hypertension), the vast majority of people over 35 have healthy pregnancies and healthy babies. The term "geriatric pregnancy" is outdated and does not reflect reality. With appropriate prenatal care and monitoring, outcomes are excellent.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
Your provider may offer early genetic screening options including cell-free DNA (NIPT) testing, which can screen for common chromosomal conditions with high accuracy. First-trimester screening with blood work and nuchal translucency ultrasound is also available. These are screening tests - not diagnostic - and the results help inform whether diagnostic testing is desired.
Prenatal care for people over 35 is largely similar to standard care, with some additional screening options. You may be offered more detailed ultrasounds. The risk of gestational diabetes and hypertension is somewhat higher, so your provider will monitor these closely.
Some providers recommend additional fetal monitoring in the third trimester for people over 35. Discussion about delivery timing may occur, as some evidence suggests a slight increase in stillbirth risk after 39 weeks in this age group. Your provider will help you weigh the evidence and make decisions that are right for you.
What Should You Do?
When to take action
- Having a healthy pregnancy over 35 - this is very common
- Normal screening test results
- Feeling anxious about age-related risks - this is understandable
- You want to discuss genetic screening options
- You have additional risk factors beyond age
- You have concerns about how your age affects your pregnancy
- Any pregnancy warning signs (bleeding, severe pain, decreased movement) apply regardless of age
- Signs of preeclampsia or gestational diabetes

Related Maternal Concerns
Anxiety About Prenatal Tests
Anxiety about prenatal tests is extremely common. Many parents feel nervous about what tests might reveal. Remember that most screening tests have a high rate of reassuring results, and even abnormal screenings often turn out to be false positives. You have the right to choose which tests you want and to decline any test. Understanding what each test tells you can help reduce anxiety.
Coping with a High-Risk Pregnancy Diagnosis
Being told your pregnancy is "high risk" can be frightening, but it simply means you need closer monitoring. Many high-risk pregnancies result in healthy babies and healthy parents. The term covers a wide range of conditions, and modern maternal-fetal medicine has excellent tools for managing most of them. Having extra support does not mean something will go wrong - it means you are being well cared for.
Dealing with Abnormal Prenatal Screening Results
An abnormal prenatal screening result can be terrifying, but it is important to understand that screening tests are designed to cast a wide net and have significant false-positive rates. Most people with abnormal screening results go on to have healthy babies after further testing confirms the baby is fine. An abnormal screening is a reason for more information, not a diagnosis.
Amniocentesis Questions and Fears
Amniocentesis is a diagnostic test performed between 15-20 weeks that analyzes amniotic fluid to detect chromosomal conditions and genetic disorders with over 99% accuracy. The risk of pregnancy loss from the procedure is approximately 1 in 500-1,000 when performed by an experienced provider. Understanding the actual risks can help you make an informed decision.
20-Week Anatomy Scan Unexpected Findings
The 20-week anatomy scan checks your baby's major organs, structures, and growth. Most scans are completely normal. When unexpected findings are identified, they range from minor variants that resolve on their own to conditions that need further evaluation. Many findings require nothing more than a follow-up ultrasound to confirm the baby is developing well.
Less Movement with Anterior Placenta
An anterior placenta (attached to the front wall of the uterus) acts as a cushion between the baby and your belly wall, which can make movements feel muffled or less intense. You may feel movement later (22-24 weeks instead of 18-20) and primarily on the sides and lower belly. This is normal, but you should still feel regular movement once it is established.
