Pregnancy milestones

In short: Pregnancy is split into three trimesters, each with its own milestones. In the first, the placenta forms, the heart starts beating and major organs develop. In the second, nausea usually fades, your bump shows and you start feeling kicks. In the third, your baby gains most of their weight and is full-term from week 37. Keep all your antenatal check-ups so your gynaecologist can follow your baby's growth.

Pregnancy is a remarkable journey, and every trimester brings unique milestones to celebrate. Whether you’re a first-time mom or adding another bundle of joy to your family, knowing what to expect can make the experience smoother and more fulfilling. Let’s explore the exciting milestones of each trimester.

First Trimester (Weeks 1–12): Building the Foundation

This is the most transformative phase for your body as it adapts to nurture new life. What’s Happening?

Your Baby:

The fertilized egg implants in the uterus, and the placenta begins forming.

By week 8, your baby’s heart starts beating, and major organs like the brain, liver, and kidneys develop.

By week 12, your baby is about the size of a lime with tiny, fully formed fingers and toes.

You:

Hormonal changes might lead to morning sickness, fatigue, and mood swings.

Physical symptoms include tender breasts, heightened smell, and frequent urination.

Care Tip: Stay hydrated and eat small, nutrient-rich meals.

Second Trimester (Weeks 13–27): The Golden Period

Often referred to as the easiest trimester, this phase lets you enjoy your pregnancy glow and bond with your growing baby. What’s Happening?

Your Baby:

By week 20, your baby is about the size of a banana and begins hearing your voice.

Facial features become more defined, and tiny movements evolve into noticeable kicks.

Your baby starts developing a sleep-wake cycle.

You:

Morning sickness fades, and energy levels return.

Your baby bump becomes visible, and you may experience occasional back pain or leg cramps.

Care Tip: Feeling those first kicks? It’s time to start light prenatal exercises!

Third Trimester (Weeks 28–40): The Final Countdown

As you prepare to meet your baby, this trimester is all about embracing the changes and getting ready for delivery. What’s Happening?

Your Baby:

Your baby’s bones are fully formed, and they gain most of their weight in these weeks.

By week 37, your baby is full-term and getting ready for the big day.

Movements may feel different as space becomes tight, but they should not slow down. If your baby moves less than usual, call your hospital straight away.

You:

Shortness of breath and difficulty sleeping are common as your baby grows.

Braxton Hicks contractions may begin, signaling that your body is preparing for labor.

Care Tip: This is the perfect time to finalize your birth plan.

Questions women ask

What are the major milestones in pregnancy?

Key milestones include the heartbeat appearing early in the first trimester, the end of the first trimester at week 12, feeling your baby move in the second trimester, the start of the third trimester at week 28, and reaching full term at week 37.

When does the baby's heartbeat start?

The heart starts beating very early in the first trimester. It can usually be seen on an early ultrasound around six to seven weeks, though timing varies. If it is not seen at your first scan, your doctor may simply repeat the scan a little later.

What happens in each trimester of pregnancy?

In the first trimester, organs form and you may feel sick and tired. In the second, energy returns, your bump grows and kicks begin. In the third, your baby puts on weight, you may feel breathless or sleep poorly, and practice contractions may start.

When is a baby full-term?

A baby is considered full-term from week 37. Many babies arrive between weeks 37 and 40, and your gynaecologist will guide you if you go past your due date.

Which pregnancy symptoms need a doctor the same day?

Go to hospital straight away for vaginal bleeding, severe tummy pain, leaking fluid, a bad headache with blurred vision, sudden swelling of face or hands, or fainting. If your baby moves less than usual later in pregnancy, call your hospital straight away; do not wait. Go the same day for fever.
