25 Weeks Pregnant: What to Expect, Weird Symptoms & How to Prep for Birth

You’re 25 Weeks Pregnant — Here’s What You Need to Know

Welcome to week 25, mama! If you’re wondering what’s normal (and what’s just plain weird) this week, you’re in the right place. From achy backs and vivid dreams to surprising changes in your gums and boobs — your body is working overtime right now. Let’s break down exactly what to expect.

 Baby at 25 Weeks: Growing, Moving, and Listening

Your baby is now around 13-14 inches long and weighs about 1.5 pounds — about the size of a full cauliflower! Here’s what’s happening developmentally:

• Fat layers are forming to help regulate temperature after birth

• Lung development continues as surfactant production begins

• The startle reflex (Moro reflex) kicks in — baby can react to loud noises

• Voice recognition begins — baby can start to recognize your and your partner’s voices!

Your Body at 25 Weeks: The Good, the Weird & the Oh-So-Normal

• Out of breath easily? Your uterus is pushing up against your lungs

• Back pain? Blame your shifting center of gravity — a pregnancy support belt helps

• Bleeding gums or nose? Hormonal changes make your blood vessels more sensitive

• Wild dreams? Thank fluctuating hormones and subconscious prep for motherhood

• Braxton Hicks? These "practice contractions" are normal if they're mild and irregular

 Your Breasts Are Prepping for Breastfeeding

Even if you’re not leaking anything, your body is already producing colostrum, a thick, antibody-rich milk called “liquid gold.” You may also notice Montgomery glands — tiny bumps on your nipples that help guide baby after birth. Yes, your body is amazing.

 Why Hydration Is Your Superpower This Week

At 25 weeks, your blood volume is up to 50% higher than before pregnancy! Staying hydrated helps prevent swelling, fatigue, and even early contractions. Not a fan of plain water? Add lemon, cucumber, or a splash of juice to stay consistent.

 Stephanie’s Pro Tip:

Start learning breastfeeding basics now — things like latching, positioning, and milk supply. Learning early helps it feel more natural later (instead of overwhelming).
