The Top 10 Early Hidden Twin Pregnancy Symptoms

Hey there, mom-to-be! Pregnancy is an incredible journey, filled with ups and downs, surprises, and unforgettable moments. I’m here to share some valuable insights about hidden twin pregnancy symptoms that I wish I had known earlier in my pregnancy. My story began with a few surprises along the way. At 18 weeks, I discovered I was carrying identical twin girls called mono mono twins. So, let’s dive into ten lesser-known signs that might save you from a few surprises of your own!

10 Surprising Early Hidden Twin Pregnancy Symptoms


1. Severe Fatigue

During a twin pregnancy, extreme fatigue can be a standout symptom. While feeling tired is quite common in pregnancy, the exhaustion you might experience when carrying twins can be different.

A blood test can help confirm a twin pregnancy by measuring the levels of human chorionic gonadotropin hormone (hCG).

Elevated hCG levels are often associated with twin pregnancies. It’s like having an overwhelming need for rest that goes beyond the usual tiredness.

If you need more naps or feel unusually drained, it could indicate that you’re expecting twins. Your body is working extra hard to support two growing babies, which can lead to heightened fatigue.

2. Intensive Morning Sickness

Morning sickness is a well-known early pregnancy symptom, but when you’re pregnant with twins, it can be more intense. Think of it as regular morning sickness on steroids. Hyperemesis gravidarum is a severe form of morning sickness often seen in twin pregnancies.

You may experience severe nausea and vomiting that might disrupt your daily life.

For me, surprisingly I did not have crazy morning sickness, but instead, I felt like I was down and out with the flu. Hot flashes, doubled-over belly aches, and super nauseous. I’m not saying this to scare you but to prepare you if your gut tells you something isn’t right.

If you struggle to keep food down or feel nauseous all day, it’s important not to ignore these persistent symptoms. Consult your healthcare provider for guidance on managing severe morning sickness.

3. Rapid Weight Gain

Hidden twin pregnancies often come with extra weight gain at a faster rate. This is because your body produces more pregnancy hormones, and your uterus grows to accommodate two babies.

An ultrasound scan during the second trimester can help identify the increased weight gain associated with twin pregnancies.

If you notice the numbers on the scale increasing rapidly, even if you’re not indulging in excessive snacks, it could be due to the changes in your body as it supports the growth of two little ones.

Before my first trimester was over, my belly popped out like I was 4 to 5 months pregnant. I thought it was because it was my second pregnancy (which could have played a part), but it was definitely because I was having twins (and didn’t know it yet)!

4. Increased Appetite

With twins on the way, you might find that your appetite increases significantly. This insatiable hunger is your body’s way of telling you it needs more nourishment to support the development of both babies. Fertility treatment may contribute to this increased appetite.

Don’t be surprised if you’re raiding the pantry more often; it’s a natural response to the increased energy demands of a twin pregnancy.

5. Strong Intuition

Listen to your gut. Sometimes, your instincts can provide valuable clues. If you feel something is different about your pregnancy, trust that intuition! An early ultrasound can provide confirmation of a twin pregnancy if you suspect it.

While it’s not a definitive medical sign, it can prompt you to seek additional ultrasounds or medical advice if you suspect you might be carrying twins.

6. Early Fetal Movements

Feeling those little flutters for the first time is one of the most AMAZING things. But if you feel it earlier than expected, it can be a delightful sign of a twin pregnancy.

Twins tend to be more active in the womb, and you might sense their movements earlier than with a singleton pregnancy (single baby).

Those early kicks and flutters can be a wonderful reminder that you have two little ones growing inside you. I felt the flutters for the first time before my first trimester ended.

7. Higher hCG Levels

Human chorionic gonadotropin (hCG) is a hormone produced during pregnancy. In twin pregnancies, hCG levels may be higher than in singleton pregnancies.

An AFP test can also help determine elevated hCG levels during the following weeks of pregnancy; first and second trimesters.

The AFP test is a simple blood test that measures the levels of this protein in your blood. Alpha-Fetoprotein (AFP) is a special protein produced by your baby’s liver.

High levels of AFP in your blood can be a sign of certain issues, like neural tube defects in your baby or the possibility of carrying twins. In short, AFP tests help healthcare providers keep an eye on your pregnancy’s progress and ensure your baby’s development is on track.

8. Measuring Ahead

During your prenatal checkups, your healthcare provider measures the size of your uterus, often referred to as the fundal height. If you consistently measure ahead of where you should be based on your gestational age, it might indicate that hidden twins are the reason behind the larger uterus size.

If your healthcare provider does not measure you and you feel they should, ask. My OBGYN never did this throughout my pregnancy, so I never thought to measure my belly. Keep this one in mind!

9. Extreme Round Ligament Pain

Round ligament pain is normal during pregnancy, but it can be more intense with twins. This pain often feels like sharp, shooting sensations in your abdomen and around the pubic bone. If you’re experiencing severe round ligament pain, don’t hesitate to discuss it with your doctor to ensure everything is progressing as it should.

10. Visible Movement

As your pregnancy progresses, you might have the remarkable experience of seeing visible movements on the surface of your belly. These movements are a surefire sign that you may have a second baby in there, and it can be an exciting and heartwarming moment during your pregnancy journey.

Remember, every pregnancy is unique, and not all these symptoms will apply to every twin pregnancy. If you suspect you might be carrying twins or experiencing any of these signs, discussing your concerns with your healthcare provider for proper evaluation and care is important.

Other Early Pregnancy Symptoms to Look Out For


Pregnancy is a unique journey, and while some symptoms are well-known, there are other subtle signs to keep an eye out for:

Frequent Urination

While frequent urination is often associated with later pregnancy, some women experience it early on. It’s due to the increased blood flow to your pelvic area and hormonal changes.

Increased Sense of Smell

Many expectant mothers notice a heightened sense of smell early in pregnancy. This heightened sensitivity to odors can sometimes trigger nausea or aversions to certain scents.

Mood Swings

Hormonal changes can lead to mood swings. You might find yourself experiencing a rollercoaster of emotions, from elation to weepiness, and everything in between.

Food Aversions

Just as cravings are common, food aversions can also be a sign of early pregnancy. You might suddenly find certain foods unappealing or even nauseating.

Breast Tenderness

Many pregnant women experience breast tenderness as one of the earliest symptoms. Your breasts may become more sensitive, sore, or swollen due to hormonal changes.

Constipation

Hormonal fluctuations can slow down your digestive system, leading to constipation. Be sure to maintain a fiber-rich diet and stay hydrated.

Dizziness or Lightheadedness

Changes in blood pressure and circulation can sometimes result in moments of dizziness. Make sure to stand up slowly and stay hydrated.

Metallic Taste

Some pregnant women report a persistent metallic taste in their mouths, which can affect their enjoyment of food and beverages. I had this symptom with both of my pregnancies; my son and twin girls!

Skin Changes

Hormonal changes can lead to skin alterations, such as acne breakouts or a pregnancy glow. Skin can become more sensitive during this time.

Vaginal Discharge

An increase in vaginal discharge is common during early pregnancy. If the discharge is accompanied by unusual odor, itching, or irritation, it’s essential to consult your healthcare provider.

Now that we’ve explored other early pregnancy symptoms to look out for, let’s shift our focus to understanding the key differences between identical twins and fraternal twins.

Identical Twins vs. Fraternal Twins


When it comes to twins, there are two primary types to know: identical twins and fraternal twins. Understanding the difference can be essential in your pregnancy journey if you happen to be carrying twins.

Identical Twins

Identical twins, also known as monozygotic twins, occur when a single fertilized egg splits into two embryos. These twins share the same genetic material and often develop in a single amniotic sac. This unique situation can lead to a hidden twin pregnancy that might be more challenging to detect, especially if they share the same amniotic sac.

Fraternal Twins

Fraternal twins, or dizygotic twins, result from the simultaneous release and fertilization of two separate eggs. Fraternal twins typically develop in their individual amniotic sacs, making them somewhat easier to identify during ultrasounds.

Navigating the Third Trimester and Beyond


As you step into the third trimester of your pregnancy, it’s crucial to understand the distinct challenges and considerations that may arise if you’re carrying twins. So here are some things to put on your radar:

Premature Birth

Twin pregnancies are more likely to result in premature birth. Preterm babies may require specialized care in a neonatal intensive care unit (NICU), so understanding the signs of preterm labor and discussing a birth plan with your healthcare provider is vital.

High-Risk Pregnancy Monitoring

High-risk pregnancies, like those with twins, require increased monitoring. Expect more frequent check-ups, ultrasounds, and assessments to ensure the health of both you and your babies.

Lactation Consultant

Preparing for breastfeeding twins may be more complex. Consider consulting a lactation consultant to help you establish a successful feeding plan if this is something you’re thinking about.

Baby’s Heartbeat

Regularly monitoring your twins’ heartbeats during the third trimester is a key aspect of managing a twin pregnancy. Your healthcare provider will use this information to assess their well-being.

Pregnant mothers with twins are indeed in a high-risk category, but with proper care and medical attention, the challenges can be managed. Your healthcare provider will be your partner in ensuring a smooth transition into the final stages of your pregnancy, making this journey as safe and comfortable as possible for you.

Frequently Asked Questions (FAQs)


How Do I Know If I’m Carrying Twins?

Identifying a twin pregnancy often involves monitoring for certain signs, such as extreme fatigue, intense morning sickness, rapid weight gain, or a strong maternal instinct. However, the most reliable way to confirm a twin pregnancy is through an ultrasound conducted by your healthcare provider.

Are Twin Pregnancies More Complicated?

Twin pregnancies are considered higher risk due to the increased likelihood of complications like preterm birth, gestational diabetes, and preeclampsia. However, many twin pregnancies proceed smoothly with proper prenatal care and monitoring.

Do I Need to Eat More During a Twin Pregnancy?

You will likely need to increase your calorie intake during a twin pregnancy to nourish both babies adequately. Consult your healthcare provider or nutritionist to develop a balanced diet plan that meets your needs.

What Are the Delivery Options for Twins?

The delivery method for twins depends on various factors, including their positions in the womb, the type of twins, and your overall health. Options include vaginal delivery, cesarean section (C-section), or a combination. Your healthcare provider will discuss the best approach for your unique situation.

Is It More Expensive to Have Twins?

A twin pregnancy can be more expensive due to increased medical visits, potential complications, and the cost of providing for two infants. Planning your budget accordingly and exploring available financial resources, such as insurance coverage and government programs, is essential.
