Hey there mama-to-be! So you've hit the 27-week mark? That's huge - welcome to the third trimester rollercoaster. I remember when I was 27 weeks pregnant with my second, it felt like crossing some invisible finish line where suddenly everything got real. Really real. Like "holy cow I need to figure out car seats and actually pack a hospital bag" real.
This 27 weeks pregnant week by week guide is exactly what I wish I'd had back then. No fluff, just real-talk about what's happening inside you, what symptoms might surprise you (hello lightning crotch!), and how to actually enjoy these last months before baby arrives.
Your Baby at 27 Weeks: The Quick Snapshot
Right now, your little one is about the size of a head of cauliflower - roughly 14.5 inches long and weighing nearly 2 pounds. Their lungs are developing surfactant (that magical substance that helps them breathe air), and they're practicing blinking and even showing brain wave activity for REM sleep. Yeah, they're probably dreaming about your womb!
What's Really Happening Week by Week at 27 Weeks Pregnant?
Let's break down exactly what's changing each week starting from where you are now. I've put together this comparison because honestly? When you're this pregnant, you deserve clear info without having to dig through medical journals.
| Week | Your Body Changes | Baby's Development Milestones |
|---|---|---|
| 27 | Top of uterus reaches 2-3 inches above belly button • Shortness of breath increases • Braxton Hicks might feel more noticeable | Lungs producing surfactant • Sleep/wake cycles established • Can now hiccup (you'll feel tiny rhythmic jumps!) |
| 28 | Kicks become stronger (maybe even painful!) • Backaches intensify • Colostrum might start leaking | Eyes can perceive light through womb • Brain developing billions of neurons • Weighs about 2.2 lbs |
| 29 | Rib cage discomfort common • Leg cramps may increase • Dark linea nigra appears on belly | Muscles and lungs maturing rapidly • Head growing to accommodate brain • Baby now regulates body temperature |
| 30 | Frequent urination peaks • Swollen ankles/feet common • Belly button may pop out | Lanugo hair starts shedding • Bone marrow takes over red blood cell production • Weighs nearly 3 pounds |
Notice how much changes just in this one-month window? That's why tracking your 27 weeks pregnant week by week journey matters. Things shift fast now.
Confession time: During my 28th week, I accidentally wore two different shoes to work because I was so tired. Pregnancy brain is absolutely real, and nobody warned me it could manifest as accidental clown footwear!
The Good, The Bad, and The Uncomfortable: Symptoms at 27 Weeks
Let's get real about third-trimester symptoms. Some are magical (feeling those little kicks!), others make you want to scream into a pillow.
Most Common Symptoms You'll Experience
| Symptom | Why It Happens | Pro Tips That Actually Work |
|---|---|---|
| Back Pain | Shifting center of gravity + relaxin hormone loosening ligaments | Prenatal yoga • Warm compresses • Sleeping with pregnancy pillow between knees |
| Braxton Hicks | Uterus practicing for labor (usually painless tightening) | Change positions • Drink water • Time them (call doc if >6/hour) |
| Shortness of Breath | Uterus pushing against diaphragm | Sleep propped up • Practice good posture • Avoid heavy meals |
| Swollen Ankles/Feet | Increased blood volume + pressure on veins | Elevate feet 20 mins hourly • Compression socks (ugly but lifesavers) • Reduce salt intake |
The Unexpected Symptoms Nobody Talks About
- Carpal Tunnel: Swelling can compress wrist ligaments. Try wrist splints at night.
- Lightning Crotch: Sudden zapping pains when baby hits nerves. Changing positions usually helps.
- Nosebleeds: Increased blood flow to mucous membranes. Use humidifier and saline spray.
- Vivid Dreams: Hormones + anticipation create wild nighttime stories. Journaling helps process them.
Red Flag Symptoms: Call your provider immediately if you experience: Severe headaches with vision changes • Sudden swelling in hands/face • Sharp abdominal pain that doesn't ease • Reduced fetal movement after 28 weeks • Fluid leakage (could indicate ruptured membranes).
Eating for Two: Nutrition Needs Specifically at 27 Weeks
Your calorie needs only increase by about 300-500 calories now - that's just a banana with peanut butter and a glass of milk extra! Focus on nutrient density:
| Nutrient | Importance at 27+ Weeks | Best Food Sources | Daily Goal |
|---|---|---|---|
| Protein | Baby's muscle and tissue growth | Greek yogurt, lentils, chicken, eggs | 70-100g |
| Iron | Prevents anemia and supports blood volume | Spinach, red meat, fortified cereals | 27mg |
| Calcium | Baby's bone development | Almonds, broccoli, dairy | 1000mg |
| DHA Omega-3 | Baby's brain development | Salmon, chia seeds, walnuts | 200-300mg |
Honestly? I failed miserably at eating enough iron-rich foods during my 27 weeks pregnant week by week journey. Paid for it with crazy fatigue until my midwife put me on supplements. Learn from my mistake!
Foods That Make Symptoms Worse
- Spicy/Greasy Foods: Triggers brutal heartburn (tums become your best friend)
- Carbonated Drinks: Bloating and gas pains intensify
- Large Meals: Contributes to shortness of breath - try 5-6 small meals
- Excess Sugar: Can spike blood sugar and energy crashes
Doctor Visits and Tests: What to Expect
Your appointments will become more frequent now - usually every 2 weeks until 36 weeks. Here's what happens:
Standard Checks at Each Visit
- Weight and blood pressure monitoring
- Urine sample check for protein/sugar (preeclampsia indicators)
- Fundal height measurement (checks baby growth)
- Fetal heartbeat check (that beautiful swooshing sound!)
Important Tests Around This Time
- Glucose Screening (24-28 weeks): That sugary drink test for gestational diabetes. Pro tip: Request the fruit punch flavor - it's least gross.
- Rh Factor Test: If you're Rh-negative, you'll need RhoGAM shot around 28 weeks.
- Antibody Screen: Checks for blood incompatibility issues.
- TDAP Vaccine (27-36 weeks): Protects baby from whooping cough.
I nearly passed out during my glucose test because I forgot to eat beforehand. Don't be me - have a protein-rich breakfast before heading in!
Movement Tracking: Your Baby's Activity Patterns
Around 27 weeks pregnant week by week, you'll notice more distinct patterns. Baby isn't just fluttering - they're doing full-on gymnastics!
What's Normal Movement at 27 Weeks?
- 10 distinct movements within 2 hours is typical
- Active periods often after meals or when you're resting
- Hiccups feel like rhythmic twitches (1-2/minute)
But let's be real - sometimes they have lazy days. If movement decreases:
- Drink cold juice or eat something sweet
- Lie on your left side
- Focus for 30 minutes
- Still less movement? Call your provider immediately
Prepping Your Body and Mind
The third trimester isn't just physical prep - your mental game matters too.
Safe Exercise Options
- Prenatal Yoga: Improves flexibility and breathing techniques
- Swimming: Takes pressure off joints (blissful weightlessness!)
- Walking: 30 minutes daily boosts energy and circulation
- Pelvic Tilts: Relieves back pain and prepares for labor
Avoid: Contact sports • Hot yoga • Exercises lying flat on back • Anything causing pain/discomfort
Mental Health Checkpoint
Antenatal anxiety affects 1 in 5 pregnant people. Signs include:
• Constant worry something's wrong with baby
• Trouble sleeping due to racing thoughts
• Panic attacks or obsessive behaviors
Talk to your provider if this resonates - therapy and support groups help enormously.

Common Questions About Being 27 Weeks Pregnant Week by Week
Can travel during 27th week of pregnancy?
Most airlines allow travel until 36 weeks, but check their policies. Road trips are fine with frequent breaks to walk and stretch. Avoid destinations without good medical care. My cousin traveled at 28 weeks but got stuck with swollen ankles - compression socks are non-negotiable!
Is sex safe at 27 weeks pregnant?
Generally yes, unless you have complications like placenta previa or preterm labor risk. Positions might need adjustment as belly grows. Some women experience increased libido now - thanks hormones! Others feel like a beached whale. Both normal.
Why am I so emotional at 27 weeks?
Hormone surges combined with sleep deprivation and the reality of impending parenthood. Crying at commercials is practically a rite of passage. If mood swings feel unmanageable though, talk to your provider - perinatal depression is treatable.
How much weight gain is normal?
By 27 weeks, average gain is 16-22 pounds if starting at healthy weight. But seriously? Every body is different. My OB cared more about consistent growth than exact numbers. Focus on nutrient-rich foods and staying active.
When should I start maternity leave?
Depends entirely on your job demands and energy levels. Many begin 1-2 weeks before due date. If your job involves physical strain, earlier might be necessary. Check company policies and STD coverage - paperwork takes forever!
Closing Thoughts from One Mama to Another
Navigating 27 weeks pregnant week by week can feel overwhelming some days. The heartburn, the waddling, the constant need to pee - it's a lot. But these weeks? They're magic. You're growing actual human bones and brain cells and eyelashes. How wild is that?
Track those kicks. Take bump photos even when you feel huge. And when people say "sleep now before baby comes"? Ignore them completely. Rest when you can, but don't stress about mythical sleep banks.
You've got this, mama. One week at a time.
