Challenges Essentials +1
The first trimester is a season of profound change. While you might not have a visible bump just yet, your body is working overtime behind the scenes. From the first positive test to that 12-week milestone, it’s a period of excitement, a fair bit of exhaustion, and plenty of questions.

If you're feeling overwhelmed, exhausted or just full of butterflies over what is to come, here's our practical guide to navigating sleep, nausea and energy in early pregnancy, so you don't feel like you're doing it solo. 

1. First Trimester Fatigue: Why power naps are your new best friend

In the first trimester, your progesterone levels skyrocket, which can leave you feeling more tired than you ever thought possible. Think of it as your body's way of making sure you slow down while it performs the pretty heroic task of growing a whole placenta.

  • Lean into the nap: If the afternoon slump is hitting harder than usual, don't fight it. If you can, even a 20-minute power nap or rest can reset your energy levels. Set an alarm so you don't oversleep and throw off your nighttime routine.


Can't nap?

  • Try a "quiet moment": Step away from screens, practise five minutes of deep breathing, and give your nervous system a chance to rest. It's not a nap, but it's the next best thing.

2. How to manage morning sickness in the first trimester

Despite the name, pregnancy nausea doesn't check the clock. It can strike morning, noon, or right when you're trying to fall asleep. The key is keeping your energy stable so those queasy waves don't knock you sideways.

  • Small and frequent wins: Instead of three large meals, aim for small, bland snacks throughout the day. Keeping something like plain crackers or ginger biscuits on your bedside table can help settle your stomach before you even get out of bed.
  • Set up hydration stations: We're sorry - we know it all tastes gross right now. Try some cucumber or lemon slices in your water and keep it close by to sip on periodically to keep yourself topped up.
  • Track your triggers: Some smells or foods may set things off more than others. Keeping a quick note on your phone of what helps (and what doesn't) can save you a lot of trial and error.

3. Build Your Support System Early

The first trimester is often the "quiet" phase of pregnancy, but that doesn't mean you have to navigate it alone. Even one trusted person who knows what you're going through can make a huge difference.

  • Find your safe space: Whether it's your partner, a trusted friend, or an online community, having somewhere to share your excitement (and your nerves) helps lighten the mental load as you move toward the second trimester.

  • Start a "brain dump" list: Between the hormonal shifts and the flood of new information, it's completely normal to feel a bit foggy. A running list on your phone for midwife questions, things to research, or items you'll eventually need can help clear the mental clutter. You supporting you also counts!

4. Pregnancy Sleep Tips: Create a soothing bedtime sanctuary

You don't need to worry about side-sleeping just yet (that usually kicks in during the second trimester), but now is the perfect time to build healthy sleep habits that will serve you well for the months ahead.

  • Try a "digital sunset": Your brain is probably racing with to-do lists. Try putting your phone away 60 minutes before bed and swapping the scrolling for a warm bath or a book. It signals to your body that it's time to wind down.
  • Comfort is everything: Your body temperature might be fluctuating and everything feels tender. Comfortable breathable cotton or bamboo pyjamas can help you stay cool and comfortable through the night.

5. Look Ahead with Gentle Preparation

You don't need to buy the whole nursery just yet, but whilst your mind is racing and time is passing, getting acquainted with baby sleep is well worth the time and effort while there is some energy in the tank.

Learn the basics of safe sleep: Start looking into the foundations of safer sleep for newborns. Sleep can look very different once a newborn arrives so a little prep can help.

   
Move your body gently: If you're feeling up to it, light exercise like walking or prenatal yoga can improve your mood and help you sleep better.

The first trimester can be a whirlwind of emotions, physical changes and late night google spirals. Doing practical things that make you feel genuinely good are what get you through this trimester so take a walk, eat the chips and tell salad you'll see it again in a few months time.

Frequently Asked Questions

Is it normal to be so tired in the first trimester?

Yes, completely. First trimester fatigue is one of the most common early pregnancy symptoms. Rising progesterone levels, increased blood volume, and the energy your body uses to grow the placenta all contribute to feeling exhausted. Most parents-to-be find their energy returns in the second trimester but always chat to your chosen health professional to receive personalised medical advice.

When does morning sickness usually start and stop?

Morning sickness typically starts around week 6 and peaks between weeks 8 and 10. For most people, it eases by week 12 to 14. If your nausea is severe or you're struggling to keep fluids down, speak with your midwife or doctor.

When do I start buying baby products?

There's no rush! Many parents start researching during the first trimester and begin purchasing key items in the second
trimester. Learning about different areas of baby sleep can be a great first step so you're organised and ready when the time comes.



Can I still exercise during the first trimester?

In most cases, yes. Gentle exercise like
walking, swimming, and prenatal yoga is generally safe and can actually improve
your mood and sleep. The key is to listen to your body and not push through
extreme fatigue. Always check with your healthcare provider if you have any
concerns.

A Little Note for the Journey

The first trimester is a marathon, not a sprint. Some days you'll feel like a glowing goddess, and other days you'll want to stay in your pyjamas until further notice. Both are perfectly acceptable. You're doing something incredible and it's all part of the magic and chaos of motherhood.
