OMG, I’m Pregnant! Now What? Your Ultimate Guide to the First Trimester of Pregnancy

Finding out you’re pregnant can feel like a whirlwind—exciting, surreal, overwhelming, and everything in between. Whether you’ve been trying or it’s a total surprise, that positive test kicks off a brand-new chapter. So… now what?
Welcome to your first trimester—the first 12 weeks of pregnancy. It’s a time of incredible changes (both in body and mind), and while it may come with its fair share of challenges, there’s plenty you can do to feel more informed, supported, and prepared.
What Is the First Trimester?
The first trimester spans week 1 to week 12 of pregnancy—yes, even before you’ve missed your period! It’s the foundation stage where your baby’s organs, brain, and spinal cord begin forming.
This is also when you’re likely to experience the biggest hormonal shifts, which can affect everything from your mood to your appetite (plus your bladder).
Common Early Pregnancy Symptoms
Every pregnancy is different—but here are a few symptoms many mums-to-be notice early on:
-
Morning sickness (which can strike any time of day)
-
Tender or swollen breasts
-
Fatigue that hits like a wall
-
Bloating or mild cramping
-
Food cravings or aversions
-
Mood swings
-
Frequent urination
💡 If symptoms feel overwhelming or unusual, always check in with your GP or midwife. Trust your instincts—they’re already strong.
When to See a Doctor or Midwife
Once you’ve had a positive pregnancy test, it’s time to book your first antenatal appointment—usually around 8 to 10 weeks. In Malaysia, this is when you’ll receive your “Buku Pink” and go through:
-
A full health check-up
-
Blood tests and urine sample
-
Estimated due date
-
A referral for an ultrasound (if not done in-clinic)
You don’t need to rush to the hospital the moment you find out. Just give your GP a ring and they’ll guide you through what’s next.
How Big Is My Baby Right Now?

Your baby starts as a tiny poppy seed and grows to the size of a plum by week 12. In just three months, they’ll go from a cluster of cells to a foetus with a heartbeat, facial features, fingers, and toes. Amazing, isn’t it?
First Trimester Checklist
Here’s what to focus on during these early weeks:
1. Take a Pregnancy-Safe Vitamin
Look for one with folic acid (400mcg daily) to support neural tube development.
2. Stay Hydrated and Eat What You Can
Don’t stress about perfect meals if you’re queasy—eat small, frequent snacks that feel manageable.
3. Avoid These
Raw fish, soft unpasteurised cheeses, certain cleaning chemicals, smoking and alcohol. Check with your midwife if unsure.
4. Rest Often
That bone-deep tiredness is real. If a nap calls, take it.
5. Download a Pregnancy Tracker App
Watching your baby grow week by week can be fun (and calming).
6. Plan Who You’ll Tell, And When
Some couples wait until after the 12-week scan. Others spill the beans earlier. Do what feels right for you.
Emotional Ups and Downs? Totally Normal
One moment you’re overjoyed, the next you’re weepy over a dog in an advert. Hormones can make emotions feel supercharged—but there’s no “right” way to feel.
Feeling anxious? You’re not alone. Many mums-to-be feel a mix of excitement and nervousness. Talk it out, journal your thoughts, or chat with other expecting parents. Support makes all the difference.
What If I’m Not Feeling the Glow?
Forget the Instagram-perfect pregnancy glow—it’s okay if you’re just trying to make it through the day. Between nausea, exhaustion and sudden life changes, the first trimester can be hard.
Be kind to yourself. If all you managed today was a nap and half a slice of toast, that’s still something. There’s plenty of time for nesting and glowing later.
Questions to Ask at Your First Appointment
Feeling prepped helps ease nerves. Here are a few things you might want to ask your midwife or GP:
-
Can I continue my current exercise routine?
-
What medications are safe to take?
-
When will I have my scans and tests?
-
What local pregnancy or antenatal classes are available?
You’re Doing Brilliantly
There’s no handbook for doing pregnancy “right”. The first trimester is a big adjustment, but you’re doing exactly what you need to—growing a tiny human, one day at a time.
Take deep breaths, rest often, and lean into support wherever you can find it.
