Early Signs of a Twin Pregnancy
Discovering you’re pregnant is an emotional and exciting moment but what if your symptoms make you suspect more than one baby is growing inside? Many women experience stronger or unusual early pregnancy symptoms that lead them to wonder if they might be carrying twins. While only an ultrasound can confirm a twins pregnancy, several early signs and symptoms can hint at the possibility.
Let’s explore the most common signs that may suggest a twin pregnancy and understand what they really mean.

1. Higher Levels of hCG Hormone
One of the first signs that could point toward a twins pregnancy is elevated levels of human chorionic gonadotropin (hCG) the hormone responsible for maintaining pregnancy. Women carrying twins often have higher hCG levels than those carrying a single baby. However, this alone isn’t proof of twins, as hormone levels can vary greatly from person to person. Your doctor may recommend additional tests or an early ultrasound to confirm.
2. Measuring Larger Than Expected
During prenatal checkups, healthcare providers often measure your fundal height the distance between your pubic bone and the top of your uterus. If you’re carrying twins, your uterus might grow faster and measure larger than expected for your gestational age. However, factors such as your body type or extra amniotic fluid can also affect these measurements. Still, measuring large can be an early indicator of a twin pregnancy.
3. Stronger Pregnancy Symptoms
If you feel that your pregnancy symptoms are more intense than usual, it could be due to carrying twins. Women pregnant with multiples often report:
- Extreme fatigue — because your body is working harder to support two babies.
- Increased morning sickness — higher hormone levels may trigger stronger nausea.
- Frequent urination — due to increased pressure on the bladder from multiple babies.
However, these symptoms can also occur in single pregnancies, so they aren’t a guarantee — just a potential clue.
4. Rapid Weight Gain
It’s normal to gain weight during pregnancy, but if you notice faster weight gain in the first trimester, it might be due to a twin pregnancy. This happens because of the additional placenta, amniotic fluid, and growing babies. Typically, women carrying twins gain about 10 extra pounds compared to those with a single pregnancy. Still, your doctor will help you determine if your weight gain is within a healthy range.
5. Elevated AFP Levels
An alpha-fetoprotein (AFP) test, done in the second trimester, measures a protein produced by your baby’s liver. When a woman is pregnant with twins, AFP levels are often higher because both babies produce the protein. If your test shows high levels, your doctor may suggest an ultrasound to confirm whether you’re carrying multiples or if another factor is involved.
6. Early or Frequent Fetal Movements
Some mothers of twins report feeling fetal movements earlier or more frequently than expected. While this can happen with multiples, it’s also common in women who have been pregnant before and can recognize the sensation sooner. So, while early kicks can feel exciting, they don’t always confirm a twin pregnancy.
7. Family History or Intuition
A family history of twins — especially on the mother’s side — can increase your chances of having twins, particularly fraternal (non-identical) twins. Genetics can play a significant role in multiple pregnancies. Interestingly, many mothers also describe having a strong intuition or gut feeling that they are carrying two babies — and sometimes, they’re right!
8. Unusual Tiredness and Hunger
Feeling exhausted or hungrier than usual early in pregnancy can also be a subtle hint. When you’re carrying twins, your body needs more energy and nutrients to support both babies, which can lead to constant hunger and overwhelming fatigue. Getting plenty of rest and maintaining a nutritious diet can help manage these symptoms.
9. Confirming with Ultrasound
While all these signs can raise suspicion, the only way to know for sure that you’re expecting twins is through an ultrasound scan. An ultrasound can confirm multiple heartbeats and show how many babies are developing in the womb. Most twin pregnancies are identified between 6 to 10 weeks, during your first prenatal scan.
Final Thoughts
Suspecting a twin pregnancy can be both thrilling and overwhelming. While symptoms like elevated hCG, stronger morning sickness, or extreme fatigue might make you wonder, remember that every pregnancy is different. The only reliable confirmation comes from an ultrasound performed by your healthcare provider.
Whether you’re carrying one baby or two, what matters most is maintaining your health, getting regular prenatal care, and embracing the beautiful journey ahead.
