Multiple pregnancies—including twins, triplets, or more—are becoming increasingly common. While carrying multiples does come with additional considerations, it doesn’t automatically mean your pregnancy is dangerous.
With thoughtful prenatal care and early monitoring, many women go on to have healthy pregnancies and healthy babies. Having the right support can make all the difference. This guide answers the most common questions about multiple pregnancies, providing you with the knowledge and confidence to navigate your unique pregnancy.
A “multiple pregnancy” simply refers to a pregnancy in which more than one fetus is developing in the uterus.
Twins: The most common form of multiples
Triplets: Three babies
Quadruplets or more: Four or more babies
Because each additional baby adds biological demands, pregnancies beyond twins tend to carry more risks and require more intensive monitoring.
Over the past few decades, twin and multiple pregnancies have become more common. This shift is largely driven by a combination of changing family-planning trends and advances in reproductive medicine.
Maternal age: As more women choose to have children in their 30s or later, the likelihood of releasing more than one egg during ovulation increases. Natural age-related hormonal changes can occasionally stimulate the release of multiple eggs, raising the chance of fraternal twins.
Assisted reproductive techniques: Fertility treatments such as ovulation stimulating medications and in vitro fertilization (IVF) can increase the likelihood of twins or higher-order multiples and have contributed to higher multiple-birth rates.
Because of these factors, multiple pregnancies are more common today than in past generations. Below is a breakdown of recent statistics of twins and multiples:
Natural twins: 1 in 250 pregnancies
Overall twins (including IVF): 1 in 30 pregnancies
Natural triplets: 1 in 10,000
Overall triplets (including IVF): 1 in 1350
In addition to maternal age and fertility treatments, a few other factors have been linked with a higher likelihood of multiples:
Previous pregnancies: Women who have been pregnant before — particularly those who have previously carried twins — may have slightly higher odds of a multiple pregnancy.
Family history: Genetics play a role, especially with fraternal twins. A maternal family history of twins can increase the chances.
Height and body composition: Some research suggests taller women and those with a higher BMI or larger overall body size may have a slightly increased chance of fraternal twins, possibly due to hormonal and nutritional factors. However, these associations are relatively weak and not reliable predictors.
Race and ethnicity: Twinning rates vary across populations, reflecting genetic and demographic influences rather than individual risk.
It’s important to remember that while these factors can raise the odds, they don’t guarantee a multiple pregnancy.
If you’re pregnant with twins, it’s natural to have questions about the difference between fraternal and identical twins—and how each type is conceived.
Fraternal (dizygotic) twins: Occur when two separate eggs are fertilized by two different sperm. Each twin is genetically unique, like any other siblings, and they may be of different sexes with varying appearances and traits. Fraternal twins are more strongly influenced by heredity, maternal age, and fertility treatments.
Identical (monozygotic) twins: Occur when a single fertilized egg splits into two embryos. These twins share nearly identical genetic material and are always the same sex. Identical twinning happens largely by chance and is not linked to maternal age, race, or fertility treatments.
Understanding the type of twins you’re carrying can help guide prenatal care. For example, twins who share a placenta (a situation that only happens with identical twins) often require closer monitoring throughout pregnancy.
Yes, often — but not always — in early pregnancy. Here’s how identification works:
Ultrasound clues: Sometimes, by looking at placentas and amniotic sacs, an ultrasound can suggest whether twins are fraternal or identical (two separate sacs and placentas often, though not always, signal fraternal twins).
Genetic testing (if chosen): The only definitive way to know is through genetic (DNA) testing, either prenatally (if medically indicated) or after birth.
Knowing the type helps providers monitor for certain risks more closely. For example, identical twins can share a placenta (monochorionic), which can increase the risk of complications like unequal blood flow or twin‑to‑twin transfusion syndrome (TTTS), twin growth discordance, or placental issues.

Every pregnancy is unique, but some signs tend to occur more often in multiple pregnancies than in single ones. Common early indicators of a multiple pregnancy may include:
More pronounced early pregnancy symptoms: Stronger nausea, increased fatigue, and more tender or fuller breasts due to higher hormone levels.
Rapid or early weight gain: Carrying more than one baby can lead to quicker changes in weight and belly size.
Higher hormone levels: Multiple pregnancies often result in elevated hormone markers, such as hCG, though this alone does not confirm twins.
Larger-than-expected uterus for gestational age: Early prenatal exams may reveal a uterus larger than expected, prompting additional evaluation.
However, none of these symptoms alone can confirm a multiple pregnancy. Many people carrying a single baby experience similar symptoms. The only way to confirm a multiple pregnancy is through imaging, such as an OB ultrasound. At Moreland OBGYN, we routinely perform a first-trimester ultrasound around 7 weeks, which provides reliable identification of a twin or other multiple pregnancy.
Every pregnancy is unique, and symptoms can vary widely from person to person. Some people carrying multiples may experience increased fatigue, stronger nausea, or notice abdominal growth earlier than expected. Others may have symptoms that feel very similar to those of a singleton pregnancy.
Because symptoms overlap so much, they can’t reliably indicate whether you’re carrying one baby or more. This is why early prenatal care and accurate testing are so important; they take the guesswork out of what you’re experiencing and help your care team provide the right level of monitoring and support from the start.
In many cases, the earliest way to confirm a multiple pregnancy is through an ultrasound. A first-trimester ultrasound (often performed between 6 and 8 weeks of pregnancy) can typically detect more than one embryo and confirm whether you’re carrying multiples. A first-trimester ultrasound is routinely done for each pregnancy at Moreland OBGYN.
While blood tests may show higher pregnancy hormone levels in multiple pregnancies, these results alone aren’t enough to provide a diagnosis. Imaging allows your provider to accurately determine how many babies you’re carrying and gather important information, such as whether the babies share a placenta or amniotic sac.
Multiple pregnancies are often described as “higher risk.” There are higher rates of preterm labor / delivery, gestational diabetes, and hypertensive disorders in pregnancy. Therefore, carrying more than one baby requires additional monitoring and personalized care to support both you and your babies throughout pregnancy.
Because your body is supporting multiple growing babies, your care team may watch certain things more closely, such as growth, nutrition, and signs of preterm labor. Many people with multiple pregnancies go on to have healthy pregnancies and healthy babies, especially with early prenatal care and regular checkups.
Carrying more than one baby places additional demands on your body, which can complicate pregnancy care. This doesn’t mean something will go wrong, but it does mean your care team will pay closer attention to support the healthiest possible outcome for you and your babies.
Some of the considerations with multiple pregnancies may include:
Preterm birth: Labor often begins earlier with multiples. Many multiple pregnancies deliver before 37 weeks, and the likelihood of early delivery increases with triplets or more.
Lower birth weight: Because multiples often arrive earlier and share nutrients in the womb, babies may be smaller at birth.
Growth differences: Sometimes one or more babies grow more slowly than expected, a condition known as intrauterine growth restriction (IUGR). This is more common when babies share placental space and resources.
Maternal health changes: People carrying multiples have a higher chance of conditions such as high blood pressure, gestational diabetes, anemia, or placental concerns (all of which are closely monitored during prenatal care).
Delivery considerations: Multiple pregnancies are more likely to require a cesarean delivery, particularly if babies are positioned differently or if there are growth or health concerns.
Newborn care needs: Babies born early or at a lower birth weight may need extra support after delivery, including time in the NICU for breathing, feeding, or temperature regulation.
While these considerations require closer monitoring, most complications can be identified early through regular prenatal care, allowing your care team to intervene promptly and adjust your plan as needed.

When you’re expecting multiples, prenatal care is a little more involved. Not because something is wrong, but because your body is doing something extraordinary. Prenatal care for a multiple pregnancy is tailored to your unique needs and may include:
More frequent checkups: You may see your provider more often than with a singleton pregnancy, especially as your pregnancy progresses. These visits help us monitor your health closely and address questions or concerns as they arise.
Regular ultrasounds and growth scans: Imaging allows us to monitor each baby’s development, assess growth patterns, evaluate amniotic fluid levels, and assess placental health, providing reassurance and early insight when adjustments are needed.
Specialty care when appropriate: In some situations, such as higher-order multiples (pregnancies with three or more babies) or specific medical concerns, your care may include consultation with a maternal-fetal medicine specialist. This added expertise ensures you receive advanced monitoring and support when it’s most helpful.
Nutrition guidance and supplements: Carrying more than one baby increases your nutritional needs. Your care team may offer personalized guidance on calories, protein, iron, folic acid, and other essential nutrients to help support healthy growth.
Gentle lifestyle recommendations: Rest, hydration, stress management, and activity guidance are all important parts of care. Depending on how your pregnancy progresses, your provider may suggest adjustments to help protect your energy and well-being.

Weight-gain guidelines for twins and multiple pregnancies are different from those for singletons, simply because your body is supporting more than one growing baby. While recommended weight gain is typically higher, there’s no single “right” number that applies to everyone. What matters most is steady, healthy growth over time, not perfection.
Your Moreland OB-GYN care team will tailor weight-gain and nutrition guidance to your individual needs, taking into account factors such as your starting weight, overall health, and your babies’ growth. Rather than focusing solely on the scale, we consider the broader picture, encompassing nutrition, energy levels, and fetal development, to provide guidance that feels realistic and supportive.
When expecting multiples, it’s especially important to take the following precautions:
Maintain a balanced, nutrient-rich diet that includes adequate protein, iron, calcium, folic acid, and sufficient overall calories.
Stay hydrated, as your body is supporting multiple babies and has an increased blood/plasma volume.
Prioritize rest and avoid overexertion: Fatigue may be more pronounced. However, staying active and regular exercise is encouraged if you are feeling up to it.
Attend all scheduled prenatal appointments: Close monitoring helps detect potential issues (growth discrepancy, placenta or fluid concerns, maternal health changes) early, when intervention is most effective.
Report any concerns quickly: As soon as you experience symptoms like unusual pain, bleeding, decreased fetal movement, signs of high blood pressure, or preterm labor symptoms, call your provider.
Plan for flexibility: With multiples, the pregnancy course can sometimes shift — you might need more ultrasounds, earlier delivery, or a different delivery plan depending on fetal growth, positioning, and maternal/fetal health.

When you’re carrying more than one baby, delivery planning often requires extra thought and flexibility. There is no one-size-fits-all plan to prepare for delivery. Your delivery preparation may include:
Discussing timing: Because multiples tend to be born earlier than singletons, your provider may recommend planning for an earlier delivery (depending on how the pregnancies progress).
Reviewing delivery options: Depending on the babies’ growth, position(s), placental arrangement, and maternal health, your care team will talk through whether vaginal birth or cesarean section (C-section) is safest.
Hospital/NICU readiness: If babies arrive early or require extra support (such as breathing, feeding, or warmth), it’s helpful to know ahead of time what your birth hospital offers and plan accordingly.
Flexible birth plan: With multiples, things can change — positions may shift, growth rates may differ, or one baby may be more vulnerable. A flexible plan helps keep everyone ready.
In some cases, a vaginal birth is possible with multiples. This is more likely when the first baby is positioned head-down, all babies are doing well, and there are no additional medical concerns. Your care team will carefully evaluate these factors as your pregnancy progresses.
Cesarean delivery is more common with multiple pregnancies, especially with triplets or higher-order multiples, or when babies are positioned differently, share certain placental conditions, or show signs that extra support is needed. In these situations, a cesarean birth can offer the safest path for both mother and babies.
At Moreland OB-GYN, decisions about delivery are made thoughtfully and collaboratively. We’ll take time to discuss your options, listen to your preferences, and recommend a birth plan that prioritizes safety while honoring what matters most to you.

Bringing home multiples — whether twins, triplets, or more — can be joyful, overwhelming, and everything in between. Here are common postpartum considerations and helpful tips:
Recovery may be longer or more complex: Because carrying multiples puts more strain on the mother’s body (physically, hormonally, nutritionally), postpartum recovery may require more rest, support, and time.
Feeding and care demands may be higher: Whether breastfeeding or bottle-feeding, caring for two or more newborns often means more frequent feedings, sleepless nights, and greater planning. Families often benefit from extra help at home, whether from family, friends, or a postpartum support network.
Emotional and mental health matters: The joy of multiples can be mixed with exhaustion, stress, and feelings of being overwhelmed. It’s normal, and important, to seek support, whether through lactation consultants, support groups for parents of multiples, mental health professionals, or community networks.
Monitoring babies’ growth and development: Because multiples may be smaller at birth or born early, pediatric and developmental follow-up may be more important. Regular checkups, developmental screening, and support services (if needed) help ensure healthy growth and catch any concerns early.
It’s helpful to think about your support network and plan ahead for your postpartum needs. Caring for multiples often means that a little extra help from family, friends, or community resources can make a big difference as you adjust and recover.
