What are the symptoms of twin babies?

Common Symptoms of Twin Pregnancy

Twin pregnancy comes with its own unique set of symptoms. Here are some of the most common signs that a pregnant woman may be carrying twins:

Extreme Morning Sickness: Morning sickness is common in all pregnancies, but it tends to be more severe in twin pregnancies due to higher hormone levels. Many twin moms experience intense nausea and vomiting throughout the day in the first trimester.

Extreme Fatigue: Carrying two babies leads to more fatigue than a singleton pregnancy. The body works harder to support the demands of two rapidly growing babies. Twin moms often feel exhausted in the first trimester.

Rapid Weight Gain: Expecting twins usually means gaining weight quicker than average. A twin pregnancy may result in 20-40 pounds of weight gain by full term, compared to 25-35 pounds for a singleton pregnancy.

Measuring Large for Gestational Age: The uterus expands more rapidly with twins. At prenatal visits, the fundal height often measures several weeks ahead of the actual gestation.

Excessive Hunger: With two babies to nourish, a twin mom’s caloric needs shoot up in the second and third trimesters. Feelings of extreme hunger are common later in pregnancy.

Severe Breast Tenderness: Hormones like estrogen and progesterone double with twins, causing more pronounced breast soreness and swelling early on. Breasts may feel extremely heavy and tender.

High Beta hCG Levels: In blood tests, beta hCG levels (the “pregnancy hormone”) are typically much higher with twins. Levels can be double or more than normal.

Two Heartbeats on Ultrasound: The surest sign of twins is visual confirmation through ultrasound. Two embryos with separate heartbeats will be present.

Unique Symptoms and Complications

In addition to the common symptoms above, some special issues may arise when pregnant with twins:

Preterm Labor and Early Delivery: Half of twin pregnancies deliver prematurely, before 37 weeks. Signs of preterm labor like contractions, cramping, abdominal pain, and pelvic pressure are more common.

Gestational Diabetes: Hormonal shifts of a twin pregnancy make gestational diabetes more likely. Symptoms are extreme thirst, frequent urination, blurred vision, and sugar in the urine.

Anemia: Carrying twins leads to greater risk of iron-deficiency anemia. Symptoms are extreme fatigue, shortness of breath, dizziness, pale skin, and racing heartbeat.

Preeclampsia: A potentially dangerous condition involving high blood pressure. Warning signs are headaches, vision issues, pain below the ribs, and swelling in the face and hands.

Vanishing Twin Syndrome: One fetus “disappears” in the uterus, usually in the first trimester. Bleeding, disappearing symptoms, and measure smaller may indicate this.

Twin-to-Twin Transfusion Syndrome (TTTS): A complication in identical twins when blood flow is shared unevenly through connecting blood vessels. Signs are too much or too little amniotic fluid.

Placental Problems: The placenta may separate or rupture more easily. Warning signs are heavy bleeding, abdominal tenderness, back pain, and regular contractions.

When to See a Doctor

Any concerning symptoms in a twin pregnancy warrants a prompt call to the obstetrician. Here are some urgent situations that require immediate medical care:

– Severe or persistent abdominal pain, cramping, or pelvic pressure
– Regular contractions or the sensation of the baby “balling up” prior to 37 weeks
– Sudden gush or constant leaking of fluid from the vagina
– Heavy vaginal bleeding or bleeding with clots
– Severe or continuous headache that does not resolve with rest and hydration
– Blurred vision, dizziness, or fainting
– Difficulty breathing or increased swelling in the hands and face
– Reduced frequency of fetal movement over 24-48 hours

Do not hesitate to contact the obstetrician’s office right away if experiencing any of the above. Prompt reporting of symptoms can help improve outcomes in twin pregnancies.

Lifestyle Changes and Home Care

While expecting twins, the following tips can help manage symptoms and stay healthy:

– Drink plenty of water – dehydration worsens pregnancy symptoms
– Take frequent rest breaks and put your feet up to combat fatigue
– Try eating small, frequent meals if dealing with severe nausea
– Consume plenty of iron-rich foods like red meat, greens, beans, and fortified cereal
– Practice stress-reducing activities such as prenatal yoga and meditation
– Invest in support belts, pillows, and slip-resistant shoes for body pain and swelling
– Communicate openly with your partner and loved ones about your needs
– Maintain reasonable activity, but avoid overexertion or anything too strenuous
– Attend all prenatal visits and follow doctor’s orders carefully
– Watch for preterm labor signs and call immediately with any concerns

When to Expect Symptoms

The timing of twin pregnancy symptoms often aligns with the following general stages:

First Trimester: More intense morning sickness, exhaustion, digestive issues, breast changes, frequent urination, and high hCG levels.

Second Trimester: Weight gain accelerates, sciatic nerve pain, shortness of breath, swelling in extremities, skin changes, and exaggerated pregnancy symptoms.

Third Trimester: Heaviness and swelling are more pronounced, preterm labor is more likely, discomfort increases, and delivery will happen earlier with twins.

However, every twin pregnancy is unique. Symptoms can come and go at different times for different moms-to-be. Stay in close contact with your obstetrician throughout.

Coping with Symptoms

Managing the myriad symptoms of a twin pregnancy can feel daunting at times. Here are some tips for coping day-to-day:

– Listen to your body’s cues and rest as needed
– Eat small, frequent, nutritious meals and snacks
– Stay on top of discomforts with warm baths, stretches, massage
– Drink water constantly to avoid dehydration
– Take short, frequent walks for energy, but avoid overdoing it
– Connect with other twin moms for empathy and advice
– Share feelings openly with your partner and support system
– Reduce stress and anxieties through meditation, prenatal yoga
– Adjust household responsibilities and allow others to help
– Be kind and patient with yourself – growing two humans is hard work!

When Symptoms Indicate a Problem

While most symptoms are par for the course, take action if you experience:

– Severe nausea/vomiting with inability to keep food/liquids down
– Extreme pain or constant contractions before 37 weeks
– Heavy bleeding or blood clots
– Sudden, severe swelling in hands or face
– Visual changes like blurred vision or flashing lights
– Difficulty breathing or chest pain
– Headache that won’t resolve, dizziness, fainting
– Bright red bleeding after intercourse
– Chills, fever, foul-smelling vaginal discharge (signs of infection)
– Reduced fetal movement or no movement after 24 hours

Trust your intuition. Call your healthcare provider if something does not feel right. Some warning signs need urgent medical care to prevent complications.

Getting Comfortable

As the twin pregnancy progresses, getting comfortable can become more challenging. Here are tips to ease common physical woes:

Back Pain: Heat pads, massage, warm baths, supportive pillows, low-impact exercise like swimming or walking. Avoid high heels.

Round Ligament Pain: Support belts, flexing knees to chest, massage, warm compresses, gentle stretches.

Trouble Sleeping: Pregnancy pillows for support, nap during the day, avoid caffeine before bed, meditation and breathing exercises.

Fatigue: Delegate tasks, take regular breaks, drink water, eat energizing snacks, say no to avoid overexertion.

Swelling: Put feet up, wear compression socks, increase protein intake, sleep on left side, gentle leg massages.

Heartburn: Avoid spicy/greasy foods, eat small frequent meals, don’t lie down after eating, chew gum to increase saliva.

Leg Cramps: Stretch calves frequently, massage cramped areas, stay active but don’t overdo it, drink electrolytes,apply heat pads.

Preparing for Labor

With twins, labor will likely begin earlier and progress faster. Here are tips to prepare:

– Know the signs of preterm labor and when to call the doctor
– Take a childbirth class specifically for twins
– Read up on cesarean birth since over 50% of twins are delivered via C-section
– Make a plan for your other children while you are in the hospital
– Have your hospital bags packed several weeks in advance, by 30 weeks if possible
– Communicate with your provider what pain management options you prefer, like an epidural
– Discuss delayed cord clamping and other preferences for a gentle delivery
– Have infant car seats ready and waiting – you’ll need 2!
– Make freezer meals and stock up on groceries beforehand
– Line up help for housework, meals, and errands after the babies arrive
– Rest as much as possible in the weeks leading up to delivery day
– Remind loved ones to wait for your call before visiting at the hospital

Support and Resources

Expecting and caring for twins is rewarding but also uniquely challenging. Take advantage of support and resources:

– Find a local support group for twin moms to swap advice and empathy

– Consider hiring a postpartum doula to help with newborn care

– Ask family and friends to assist with meals, rides for older kids, household chores

– Take new parent classes focused specifically on twins

– Connect with lactation specialists to establish breastfeeding

– Research helpful gear like double strollers, car seats, baby carriers

– Review your finances and insurance, as costs are higher with twins

– Check if you qualify for WIC nutritional assistance and other local programs

– Explore employer benefits like extended leave and flexible hours

– Connect with your religious or cultural community for ceremonies welcoming the twins

You’ve got this! With planning, support, self-care, and teamwork, you will handle the twin pregnancy symptoms beautifully.


Twin pregnancy comes with increased symptoms like severe morning sickness, rapid weight gain, and constant fatigue. Unique complications can arise too like anemia, preeclampsia, and twin-to-twin transfusion. Stay vigilant about concerning symptoms and call your healthcare provider if anything seems abnormal. Get plenty of rest, nutrition, and support. While challenging, remember the rewards will be double with two beautiful babies to welcome!
