7 Things They Don’t Tell You About the Second Trimester of Pregnancy

Sharing is caring!

The second trimester of pregnancy is often called the “honeymoon phase” of pregnancy. By now, many women experience relief from first-trimester nausea and fatigue, and they aren’t yet dealing with the heavy discomfort of late pregnancy. But while this middle stage of pregnancy is often seen as the easiest, there are still many surprises that no one talks about.

Between unexpected physical changes, strange pregnancy symptoms, and little-known discomforts, the second trimester of pregnancy can be full of things you didn’t see coming.

If you’re in your second trimester—or getting close to it—this post will help you prepare for what’s ahead. Here are seven things no one tells you about the second trimester of pregnancy (but definitely should!).

1. Round Ligament Pain Can Stop You in Your Tracks

Just when you thought you’d left first-trimester discomfort behind, here comes round ligament pain—one of the most common (and jarring) second-trimester symptoms.

What does it feel like?

• A sharp, sudden pain in your lower belly, groin, or hips
• A pulling or stabbing sensation when you stand up, roll over in bed, or move too quickly
• Occasional aches and twinges as your belly grows

Why does it happen?

Your uterus is expanding rapidly, and the round ligaments (which support the uterus) are stretching to accommodate this growth. These ligaments tighten and pull when you move suddenly, causing brief but intense pain.

How to relieve it:

• Move slowly when getting up or changing positions
• Support your belly with a maternity support band
• Stretch regularly -gentle prenatal yoga can help (I highly recommend downloading this app -use the code ALIFEINLABOR– for all of your pregnancy and postpartum workout needs. It's a game changer and has loads of yoga, weight lifting, and other workouts for pregnant and postpartum moms)

While it can be uncomfortable, round ligament pain is completely normal and a sign that your body is adjusting to your growing baby.

2. Your Baby Bump Might Be Smaller (or Bigger) Than Expected

Everyone imagines a perfectly round, adorable baby bump by the second trimester of pregnancy. But in reality, bump size varies a lot from person to person. What's surprising about this is how self-conscious you might become about the size of your bump because of what other people's perception of its size is.

Why does bump size differ?

• First pregnancy vs. subsequent pregnancies – First-time moms may “show” later.
• Body shape and torso length – A longer torso may hide a bump longer, while a shorter torso may show earlier.
• Position of the baby and placenta – A baby positioned closer to the spine or an anterior placenta (placenta in front of the uterus) can make the bump less noticeable.

What to remember:

• A small bump doesn’t mean your baby isn’t growing properly. Sometimes it just takes extra time for that “pop”.
• A large bump doesn’t mean you’re having a huge baby. The reality is that most people can't distinguish a “term” pregnancy from a “preterm” one. Don't be surprised if someone tells you that “you must be due any day now!” when you literally have 3 more months to go.
• Every pregnancy is unique, and bump size isn’t a reliable indicator of your baby’s health.

Trust your doctor or midwife to monitor growth and reassure you that everything is on track!

3. Your Skin Might Freak Out Instead of “Glowing”

You’ve probably heard about the pregnancy glow, but what people don’t mention is that hormonal skin changes can go in the opposite direction. Instead of glowing, some women experience:

• Hormonal acne [solution]– Breakouts can worsen, even if you never had acne before.
• Melasma (“pregnancy mask”) [solution]– Dark patches of pigmentation, usually on the face.
• Dry, itchy skin [solution]– As your belly grows, your skin stretches, leading to dryness and discomfort.

How to manage it:

• Use pregnancy-safe skincare (avoid retinoids and harsh chemicals).
• Apply sunscreen daily to prevent melasma from worsening.
• Keep skin moisturized with gentle, hydrating products.

These changes usually fade after pregnancy, but in the meantime, a consistent skincare routine can help keep your skin feeling its best.

4. You'll Start Feeling Fetal Movement—But it may Not be What You Expect

Feeling your baby move for the first time is one of the most magical moments of pregnancy. But at first, fetal movement might not feel the way you imagined.

When will you feel movement?

• Most women feel their baby between 16-22 weeks.
• First-time moms may notice it later, while second-time moms often recognize movement earlier.

What does it feel like?

• Gentle flutters, pops, or tiny bubbles (not strong kicks right away).
• More noticeable after meals or when lying still.

Things to keep in mind:

• Anterior placenta? Your placenta’s position can cushion kicks, making movement harder to detect. But that doesn't mean you won't feel them at all. It just means that they might be more dull or hard to notice.
• Movement might be inconsistent at first—your baby is still small!

By the end of the second trimester, those tiny flutters will turn into strong, unmistakable kicks.

5. Your Sex Drive Might Skyrocket—or Disappear

Pregnancy hormones can have wild effects on libido, and the second trimester of pregnancy is often when those changes become most noticeable.

Some women experience:

✔️ Increased sex drive due to more blood flow to the pelvic area

✔️ More intense sensations because of heightened sensitivity

Others experience:

❌ A total loss of interest due to body changes, discomfort, or exhaustion

Either way, it’s normal. Communicate with your partner about how you’re feeling, and remember—your body is going through huge changes!

6. Leg Cramps and Restless Legs Can Keep You Up at Night

Just when you thought you’d finally get some sleep after the first trimester, leg cramps and restless leg syndrome (RLS) can strike.

Leg cramps:

• Sudden, painful muscle spasms (often in the calves) that wake you up at night.
• Caused by weight gain, circulation changes, and possible magnesium deficiency.

Restless Leg Syndrome (RLS):

• A strange urge to move your legs, usually at bedtime.
• Feels like tingling, itching, or crawling sensations in your legs.

How to relieve it:

• Stay hydrated and stretch before bed.
• Try magnesium supplements (check with your provider first).
• Elevate your legs and use a warm compress before sleep.

These symptoms usually improve after birth, but they can make the second trimester of pregnancy more exhausting than expected.

7. Vivid Dreams Are Surprisingly Common

Pregnancy dreams can be wild, emotional, and downright bizarre—and they tend to get more intense in the second trimester.

Why?

• Increased REM sleep (pregnant women sleep lighter and wake up more).
• Hormonal fluctuations can trigger more vivid dreams.
• Anxieties about birth and motherhood often show up in dreams.

How to cope:

• Keep a journal if dreams are affecting your emotions.
• Practice relaxation techniques before bed.
• Remember—it’s just your brain processing all the big changes ahead.
