Your Pregnancy Journey, Trimester by Trimester


First Trimester (Weeks 1-12)
This is the all-important stretch where your baby's major organs are starting to form. You might feel a bit off—thanks, morning sickness—but it's all for a good cause! Now is the time to start taking prenatal vitamins and focussing on a healthy diet.


Second Trimester (Weeks 13-27)
Ah, the honeymoon phase! Most mums find they've got more energy, and you might even start to feel baby’s first kicks. This is a good time to have those important scans and tests to make sure your little one is doing just fine.


Third Trimester (Weeks 28-40)
As you near the finish line, your body's working hard to prepare for baby's arrival. You'll likely feel a few aches and pains as your baby grows. Don't forget those prenatal check-ups and maybe even a birthing class to get ready for the big day.


Emotional Well-being is Key

Let's not forget about your emotional health. Pregnancy can be a rollercoaster of emotions, so don't hesitate to seek support. Whether it's from loved ones, support groups, or professionals, you're never alone on this journey.

As you get closer to meeting your bundle of joy, it's time to pack that hospital bag and stock up on baby essentials. And remember, your journey doesn't end with the birth; postpartum care is equally crucial. So take your time to rest, attend postnatal check-ups, and embrace the beautiful chaos that comes with being a new mum.

Our Due Date Calculator is based on a 28-day cycle, but we know every woman is unique, so cycle lengths can vary. While our calculator gives you a handy estimate, it’s not a substitute for medical advice. So make sure you consult your healthcare provider for the most accurate information.

Your Pregnancy Journey: A Week-By-Week Guide & Pregnancy Milestones 

Let's dive into the incredible journey of your pregnancy, week by week. Isn't it amazing to think you're growing a new life inside you? Let's see what's happening at each stage:

Week 1: This is where it all begins, but hold your horses! Conception hasn't even happened yet. We start counting from the first day of your last period, and your body is already getting ready for that magical moment of ovulation.

Week 2: At this stage, an egg is waiting for its perfect match— a sperm, of course! Your body is busy setting the stage for the big ovulatory grand entrance.

Week 3: And action! This is the week when your fertilised egg cozies up in your uterus. Your body starts producing hCG hormone, and voilà, the first symptoms of pregnancy like a missed period and nausea might make an appearance.

Week 4: Yay, you could get a positive pregnancy test now! Your future little one has found their home for the next eight months in your womb.

Week 5: By now, your period is most likely missing in action, and those hormonal changes may be making you feel a bit queasy and tired.

Week 6: Hello, morning sickness! You might be feeling a tad under the weather thanks to all those hormonal shifts. 

Week 7: Your pregnancy symptoms are going full throttle, and your uterus is nearly doubling in size. 

Week 8: Time for your first midwife visit to get all the necessary tests. 

Week 9: Your baby is about the size of a grape, and starting to look more human. Joints are flexing and taste buds are forming.

Week 10: Most of your baby's vital organs are formed and they're growing rapidly. Your baby can now move those tiny arms and legs.

Week 11: Your baby is now 2 inches long! The skin is so translucent you could almost see a network of vessels through it.

Week 12: Get ready for your baby's first "photo" during your ultrasound! Your little one now has vocal cords and is starting to produce urine.

Week 13: You're closing the chapter on your first trimester! The early pregnancy symptoms may soon be a distant memory.

Week 14: Soon enough, you'll feel your baby's first kicks.

Week 15: You might start to notice a 'baby bump' as your uterus moves up. Time to do some pregnancy shopping?

Week 16: Four months down! Your little human is not so little anymore, and things are really picking up pace.

Week 17: You're likely starting to show more. Your baby is growing rapidly and even making facial expressions!

Week 18:*Get ready for some big developments like yawning, stretching, and a growing sense of taste in your baby.

Week 19: Your rounded belly is hard to miss! Sensory areas in your baby's brain are rapidly evolving.

Week 20: Halfway there, mum! Your baby's legs are almost straightened out. Now's the time they'll be measured from head to toe.

Week 21: Past the halfway mark! You can definitely feel your baby exploring her new home.

Week 22: Your pregnancy is blossoming! Your baby is now the size of a spaghetti squash and kicking more frequently. You might start to notice stretch marks as your skin stretches to accommodate your growing bump. 

Week 23: This week is truly amazing as your baby's face is fully formed now! You might even catch a glimpse of this during a 3D ultrasound. You're probably also experiencing 'pregnancy brain,' but don't worry, it's all part and parcel of the journey.

Week 24: You might be dealing with some leg cramps or back pain. Time for a relaxing soak or a massage, perhaps?

Week 25: Your baby's wrinkles are smoothing out as they put on baby fat. You're around 5 months and 3 weeks pregnant now! Have you begun planning your maternity leave? It might be a good time to sort that out.

Week 26: You might have an antenatal appointment this week. Your midwife might measure your blood pressure and test your urine, among other things. Your baby's hearing is improving; try chatting or singing to them!

Week 27: You're rounding off the second trimester and entering the home stretch. Now's the time to attend some antenatal classes if you haven't already. They're a great way to prepare for labour and meet other mums-to-be.

Week 28: Welcome to the third trimester! Your baby can now open their eyes and might even respond to light. Are you feeling breathless? That's because your uterus is nearly at rib-cage level now.

Week 29: Time to keep an eye on your baby's movements, which should be fairly regular now. You might also be feeling the infamous 'Braxton Hicks' contractions as your body prepares for the big day.

Week 30: Aches and pains might be your constant companions now. Treat yourself to a warm bath or ask your partner for a gentle massage. Your baby is practising breathing movements, even though their lungs are not yet fully mature.

Week 31: Your body's going into nesting mode, and you might find yourself cleaning and organising everything in sight. Your baby can turn their head and their senses are developing rapidly.

Week 32: Your baby's taking up more and more room, which might mean some discomfort for you. You might find it hard to sleep or get comfy. Hang in there, you're doing great.

Week 33: If your baby is head-down, well done, little one! Have you packed your hospital bag yet?

Week 34: Your body's gearing up for birth. You might have more frequent Braxton Hicks contractions. Have you decided on a birth plan? It might be the time to finalise it with your healthcare provider.

Week 35: Your baby's kidneys are fully developed, and their liver can process waste products. Not long to go now! Are you having any cravings? Go ahead, indulge a little, you deserve it.

Week 36: Most of the baby's development is complete, and you might feel a little lighter as the baby 'drops' into your pelvis. Time to double-check that hospital bag and make sure you're all set.

Week 37: Yay, you're considered full term! Your baby is ready to make an appearance any day now. 

Week 38: Frequent loo trips are your life now as the baby presses against your bladder. It's also a good time to rest and save up energy—you'll need it soon!

Week 39: Baby could arrive at any time! If you're feeling impatient, try to relax. 

Week 40: Your due date's here, and it's come and gone? Hang in there, lovely, your bundle of joy will arrive when they're ready, and it'll be magical.

Pregnancy Nutrition

When you're pregnant, every bite counts. Nutrition during pregnancy is a topic that's often surrounded by myth, hearsay, and even a sprinkle of grandmother's wisdom. So, we're here to serve up the facts in a warm and friendly dish of helpful advice.


The Importance of Balanced Nutrition

Your body is performing a little miracle—growing a human from scratch! To nourish your little bundle of joy, it's crucial to maintain a balanced diet that includes the right mix of vitamins, minerals, and essential nutrients.


The Fab Five

Let's break it down to the core elements. A balanced pregnancy diet typically includes:

1. Protein: Fish, lean meat, and eggs are great protein sources. If you're vegetarian or vegan, tofu, legumes, and nuts should be on your radar.

2. Calcium: Your baby's bones are forming, so make sure to include dairy or fortified plant-based milk in your diet.

3. Iron: Your blood volume increases during pregnancy, and iron is key to avoiding anaemia. Dark leafy greens and lean meats are your go-to sources.

4. Fibre: Keeping the digestive system moving is essential when you're pregnant. Load up on fruits, vegetables, and whole grains.

5. Folate: This vitamin is essential during the first trimester to help prevent neural tube defects. Lentils, avocados, and dark green veggies are fab folate foods.

Keep Hydrated

It's not just about what you eat but also what you drink. Dehydration can lead to complications, so aim for at least eight cups of water a day. Feel free to enjoy the occasional herbal tea as well, but stay clear of too much caffeine and avoid alcohol entirely.

Snacking Smart

When those cravings hit, and oh, they will, try to reach for healthier options. Swap crisps for carrot sticks or opt for a fruit salad instead of a chocolate bar. It's all about balance, though, so don't beat yourself up for the occasional indulgence.

Foods to Avoid

- Raw seafood and undercooked meat
- High-mercury fish like shark, swordfish, and king mackerel
- Unpasteurised dairy and juices
- Excessive caffeine and any amount of alcohol

A Final Note

Always consult with your healthcare provider before making significant changes to your diet, especially during pregnancy. They can offer personalised advice that's tailored just for you and your baby.

So there you have it, a little guide to help you navigate the wonderful but sometimes confusing world of pregnancy nutrition. Remember, you're not eating for two adults; you're eating for one amazing, growing baby. Here's to a nourished and fabulous pregnancy journey! Cheers! 🌸


There you go, a week-by-week guide to your magical pregnancy journey. And remember, every pregnancy is unique, so take it all one step at a time. Sending lots of love and positive vibes your way!
