You are 32 weeks. You can't put your own socks on without sitting down. You haven't slept on your back in 12 weeks. Your feet swelled up after a five-minute walk to the post office. You felt the baby do something this morning that may or may not have been hiccups but might also have been her trying to break out through your ribs.
The third trimester is the part of pregnancy nobody actually photographs honestly. It's also the part where your body gives you the most new symptoms you've never had before, and you spend a lot of time wondering whether each one is normal or whether you should be on the phone to triage.
Here is the honest breakdown.
What's normal from week 28 onwards
These are all common and almost always fine, even when they feel dramatic.
1. Braxton Hicks contractions
Tightening across the bump that comes and goes, usually painless or mildly uncomfortable, often triggered by dehydration or activity. These are practice contractions. Normal from around week 20 onwards, more frequent in the third trimester. Drink water, lie down for 30 minutes. If they ease, it's Braxton Hicks.
2. Swelling of feet, ankles, hands
Mild swelling, especially by the end of the day, especially in hot weather, is normal. Your blood volume is up almost 50%. Fluid pools. Elevate your feet, drink water, don't stand for long periods.
3. Hip and pelvic pain
Your ligaments are relaxing in preparation for birth. Pubic symphysis pain, sciatica, hip aches, all normal. Pregnancy yoga, warm baths, a support belt, and side-sleeping with a pillow between your knees all help. If it's so severe you can't walk, mention it to your midwife.
4. Heartburn that wakes you up
The baby is now pushing your stomach upwards. Acid escapes. Eat smaller, more frequent meals. Avoid eating in the 2 hours before bed. Sleep slightly propped up. Tums or Gaviscon are generally fine in pregnancy but check with your pharmacist or GP for the dose.
5. Insomnia even though you're exhausted
The most cruel third-trimester symptom. You are tired all the time but can't sleep when you finally lie down. Common reasons: pelvic discomfort, heartburn, the baby being active at night, anxiety about the birth, frequent need to wee. Almost nothing fixes it entirely. A good pregnancy pillow, an audiobook with a sleep timer, and an honest acceptance that some nights will just be hard.
6. Vivid, scary dreams
If anything, the dreams get more intense in the third trimester. Sometimes nightmares about the birth, the baby, things going wrong. Your brain is processing the upcoming change. The dreams do not mean anything will go wrong.
7. The Lightning Crotch
Sharp, electric-shock pain in your pelvis that lasts a second or two. Caused by the baby pressing on a nerve. Sounds alarming. Is normal. Doesn't mean labour is imminent.
8. Increased Braxton Hicks and "false labour"
From around 36 weeks, many people have contractions that come every 10 minutes for an hour, then stop. This is your body practicing. Real labour contractions get stronger and closer together over time, not weaker.
9. Movement patterns change
The baby has less room. Movements become slower and more rolling rather than sharp jabs. As long as you can feel her moving a normal amount every day, this is fine.
When to actually call your midwife
This is the section to bookmark. These signs mean call, don't wait, don't post in a Facebook group.
Call straight away (or go to triage) if:
- You can't feel her moving after drinking a cold sweet drink and lying still on your side for 30 minutes. Reduced movement is the single most important warning sign in the third trimester. Don't wait.
- You have severe headaches that don't ease with paracetamol, especially with vision changes, swelling of your face, or a feeling of unwellness. Possible preeclampsia.
- Sudden, dramatic swelling in your face, hands, or feet (different from the gradual end-of-day puffiness).
- Pain in the upper right side of your abdomen (under your ribs). Also a preeclampsia sign.
- Bleeding of any amount, especially with pain.
- A gush of fluid or a slow steady leak from your vagina. Could be your waters breaking. Pad it, note the colour, call.
- Itching that won't stop, especially on your hands and feet, especially at night. Possible obstetric cholestasis.
- Reduced movement again after a check-up where you were told everything was fine. The single check is not enough. Every day matters.
Call within 24 hours if:
- Heartburn that suddenly becomes much worse
- A persistent dull headache
- A new pain you're not sure about
- Your blood pressure reading at home is above 140/90
- Any new symptom that's making you anxious
A midwife would rather hear from you 10 times and reassure you 9 times than miss the one time it matters. Use them.
What to actually prepare in the third trimester
The third trimester is the practical-prep trimester. The big to-do items:
1. Pack your hospital bag. By week 36 at the latest. One for you, one for baby, one for partner. 2. Wash baby clothes in fragrance-free detergent. Sort them by size. 3. Install the car seat. Have a mechanic or fire station check the fitting if you're not 100% confident. 4. Sort the first few weeks of meals. Freezer meals, batch cooks, easy options. You will not want to cook in the first 2 weeks. 5. Write your birth preferences (not a "plan" — a list of what matters to you if everything goes to plan). 6. Have the conversation with your partner about night feeds, visitors, mum-and-baby boundaries. 7. Get the pram, the cot, the basics. Now's the time. 8. Sleep when you can. Genuinely. The third-trimester insomnia is also preparing you for the postpartum sleep deprivation. Bank rest when possible.
What you actually need to hear
The third trimester is uncomfortable in ways that don't always look serious from the outside. Insomnia is invisible. Heartburn is invisible. Pelvic pain is invisible. Anxiety about the birth is invisible. You are doing more work in your body right now than at any point so far in the pregnancy, and society mostly responds by asking when you're due.
You are not weak for finding this hard. You are not failing for crying about your swollen ankles at 2am. You are growing a complete person while also working, parenting other children, running a household, and possibly still tying your own shoes.
Take it slow. Sleep when you can. Eat what works. Call your midwife at the first sign of any of the warning list. Pack your bag. Write the list. Then wait, in whatever calm pieces you can find.
She's coming. You're ready, even on the days you don't feel ready. You've got this.
