6 Weeks Pregnant: Symptoms, Emotions, What to Expect & What to Do

At 6w pregnant, many mums start noticing early pregnancy signs like feeling sick, extremely tired, emotional, or having sore breasts. Even if your belly doesn’t look different yet, your body is already working really hard to help your tiny baby grow.

Hey mama!

Congratulations, you’re officially 6 weeks pregnant!

If you’re anything like me, this stage is a whirlwind of excitement, fear, disbelief, and total confusion.

Honestly, I couldn’t believe it myself when I first saw that positive test. (In my case, there were twins, but that’s a story for another time lol.)

At 6 weeks, your body and emotions may already be changing a lot, even if you don’t look (or feel) pregnant yet.

You may be asking yourself: “Is this real? Am I ready? What even happens now?”

(If this is your first baby, my first pregnancy guide on what to expect can help you see the bigger picture.)

No need to worry, mama.

All of these feelings are normal, and pretty understandable because it can be difficult to wrap your head around the fact that you have a little human growing inside of you!

6 weeks pregnant: quick overview

• Week: 6 weeks pregnant
• Trimester: First trimester
• Baby size: Lentil (about 4–6 mm or 0.16–0.24 inches long)
• Baby development: Heart beating, brain and spinal cord forming
• Common symptoms: nausea, fatigue, sore breasts, new emotions, bloating
• Belly changes: Usually no visible bump yet (bloating is common)
• Doctor appointment: : Many women schedule their first midwife visit around this time

Even though your belly may not look different yet, a lot is happening at 6 weeks pregnant, both in your body and in your baby’s development.

Emotional changes at 6 weeks pregnant

When you’re pregnant, it’s not just your body that’s changing and adjusting – it’s also your mind, your heart, and every tiny fear and hope you carry.

At 6 weeks, you likely experience a wild rollercoaster of emotions.

Here’s what it might feel like:

Shock & disbelief

When I first found out, I couldn’t wrap my head around it.

I remember staring at my belly and thinking: “Is it real? There’s a baby in there?”

It takes time to accept the reality of (first) pregnancy.

Some days it feels like a dream.

Other days, doubts creep in: “Am I ready for this? What if something goes wrong?”

Both are normal.

And it takes time to accept that life has shifted forever.

Anxiety & fear

At this stage, you may worry about miscarriage.

You may lie in bed at night, heart racing, thinking, “Is my baby going to be okay?”

Every cramp, every twinge, every missed snack feels like a warning.

Your brain is doing its best to protect you, but it sure can be mentally exhausting.

Emotional ups & downs

They call it “mood swings” but I think this term doesn’t give it justice.

You might feel excited one minute, hopeless the next, and feel guilty for either.

At 6 weeks it isn’t just “hormones” – it’s your body and mind adjusting to a life changing journey.

But these intense emotions are part of the process.

They don’t mean you’re crazy or a bad person, they mean you’re pregnant.

Tiny moments of bonding

Even if it doesn’t feel like it yet, the bond with your baby is quietly forming.

You might daydream about them, imagine their tiny faces, or feel a strange protective urge.

These moments are fleeting now, but they grow stronger each week – now and long after your baby arrives.

What trimester is 6 weeks pregnant?

At 6 weeks pregnant, you are in the first trimester.

The first trimester lasts from week 1 to week 12 and is when the biggest developmental changes happen for your baby.

This is also the time when many pregnancy symptoms appear, including fatigue, nausea, and emotional changes. (more on that later!)

What does a 6 week pregnant belly look like?

At 6 weeks pregnant, most women don’t have a visible baby bump yet.

Many women only start showing sometime in the second trimester.

Your uterus is still very small, so any changes you notice are usually caused by bloating rather than the baby itself.

Some women feel:

• slight lower belly fullness

• bloating after meals

• tightness in clothes

Even if nothing has changed on the outside, your body is already doing incredible work on the inside.

Your baby at 6w pregnant

At 6 weeks pregnant, your baby (now called a fetus) is about the size of a lentil (around 4 – 6 mm long).

Even though your bump isn’t showing yet, there are incredible things happening inside your body.

Your baby is developing:

• The heart has started beating and pumping blood

• The brain and spinal cord are forming

• Tiny arm and leg buds are beginning to appear

• Early facial features like the eyes and nose are developing

• Major organs such as the lungs, liver, and kidneys are starting to form

It may not feel real yet, but your body is already working incredibly hard to support this tiny life.

6 weeks pregnant symptoms: what’s normal

At 6 weeks pregnant, many women start experiencing early pregnancy symptoms caused by rising hormones and your body adjusting to pregnancy.

Every pregnancy is different, so you may experience many of these pregnancy symptoms, only a few, or none at all.

Physical symptoms:

• Morning sickness (nausea or vomiting) – this can happen at any time of day, not just mornings.

• Extreme fatigue – your body is using a lot of energy to support early pregnancy, so it can feel like you’ve taken a double dose of sleeping pills.

• Tender or swollen breasts – hormonal changes increase blood flow to the area.

• Frequent urge to pee – your kidneys are working harder and your uterus is growing.

• Heightened sense of smell – certain foods or smells may suddenly feel overwhelming.

• Light spotting – early pregnancy spotting can sometimes occur.

Please note that some women feel very few or no symptoms at all at 6 weeks – and that is also completely normal and doesn’t mean anything is wrong.

In fact, you are very lucky and most mums probably envy you! 😉

Emotional symptoms:

• New emotions – shifting hormones can make emotions feel stronger than usual; they can also be weird or scary.
• Worry, especially about miscarriage – the first few weeks are always uncertain in terms of whether the embryo will survive, so it’s completely understandable if you worry about having a miscarriage.
• Intrusive thoughts – these are unwanted, often disturbing thoughts that pop into your head out of nowhere, and they are extremely common in pregnancy. Interestingly, they are actually your brain’s way of protecting you.
• Excitement mixed with fear – not only about birth, but also about the future, finances, health, and everything else that every new parent thinks about.

Mini milestones you can celebrate

Even at 6 weeks, there are little victories worth noticing and celebrating:

• You survived your first week of nausea

• You made it through the anxiety spiral about miscarriage

• You started being aware and/or talking about your feelings

Every step counts.

You’re learning how to navigate this massive transformation – and that’s huge.
