Pregnancy after 35 is often called advanced maternal age. For many women, it’s a time of careful planning and heightened awareness. While most pregnancies in this age group are healthy, the placenta—the lifeline between you and your baby—deserves extra attention. After 35, the risk of placental complications like insufficiency, abruption, or previa does increase. The key is not to panic, but to know what your body is telling you. Here are three warning signs that warrant a call to your provider, without delay.
1. A Sudden Change in Your Baby’s Movement Patterns
Feeling your baby move is one of the most reassuring parts of pregnancy. In the third trimester, you should feel a consistent pattern of kicks, rolls, or jabs—not necessarily a specific number, but a rhythm that feels normal for your baby. A significant decrease in movement, or a complete stop, can indicate that the placenta is not delivering enough oxygen or nutrients.
If you notice fewer than 10 movements in two hours while lying on your side (after eating or drinking something cold), call your midwife or go to the hospital. This is a standard kick-count guideline used by many providers.
Trust your gut. If something feels “off,” never wait until the next day. A non-stress test (NST) or a biophysical profile (BPP) can quickly check placental function and your baby’s well-being.
2. Vaginal Bleeding That Is Not from a Routine Exam
Any vaginal bleeding in the second or third trimester should always be evaluated. For pregnant women over 35, two placental conditions are more common: placenta previa (the placenta covers the cervix) and placental abruption (the placenta detaches from the uterine wall before delivery).
The bleeding of abruption is often—but not always—accompanied by a steady, intense abdominal pain or a tight, board-like feeling in the uterus. Previa bleeding is usually painless and bright red. Both can happen after exercise, sex, or seemingly out of nowhere. Any bleeding that soaks a pad in an hour, or is accompanied by cramps, back pain, or contractions, is a medical emergency.
3. Severe Swelling, Headaches, or Vision Changes (Related to Placental Function)
Placental issues aren’t always directly about bleeding or movement. Sometimes, the placenta triggers dangerous blood pressure changes. Preeclampsia, which often involves placental dysfunction, shows up with symptoms that can be mistaken for “normal pregnancy discomfort.” Symptoms include a persistent headache that doesn’t get better with acetaminophen, changes in your vision like blurriness or flashing lights, sudden swelling in your face or hands, and pain under your ribs on the right side.
The connection? A poorly functioning placenta releases substances that damage the mother’s blood vessels. This is why preeclampsia is taken seriously—it can affect the placenta’s ability to support your baby. If you have a history of high blood pressure or gestational diabetes, the risk is even higher.
When to Seek Help Immediately
- No fetal movement after focused kick counts.
- Vaginal bleeding that is more than a few spots.
- Severe headaches that do not go away after rest.
- Sudden swelling in your face, hands, or feet.
- Labor-like pain before 37 weeks (possible placental abruption).
You do not need to be a medical expert. These three warning signs—changes in movement, unusual bleeding, and certain physical symptoms—are your brain and body asking for a check-up. Because of your age, your medical team will likely be more proactive with growth scans and blood pressure monitoring. Lean into that. Extra scans are not a sign of failure; they are a sign of wisdom.
Most placental issues can be managed or delivered early if caught soon enough. Your job is to notice and speak up. The placenta may be an unseen organ, but it communicates every single day. Listen for these three signals.
