Baby development at 8 weeks

At eight weeks, your baby is growing very quickly.

How big is your baby at 8 weeks?

At this point, they are about ½ to ¾ of an inch long, or about the size of a peanut.

And they are growing fast!

In fact, your baby is growing about a millimeter in size each day.

They’re also changing shape.

After starting off as a teeny tiny fertilized egg, the embryo at 8 weeks (yup, the technical term for your baby is “embryo” until the 11-week mark!) has grown different body parts from diversifying cells.

At this point, your baby already has a heart, the beginnings of arms and legs, a “neural tube” and… wait for it… a tail!

Starting at 8 weeks, that “neural tube” will turn into the brain, spinal cord and major nerves.

Webbed fingers and toes are developing (they’ll separate later) and your baby’s arms can bend at the elbows.

Also at this time, your baby’s facial features ‒ such as their ear lobes, nose, eyelids and upper lip ‒ are forming, as well as the retina (the layer of cells in the eye that processes light).

Slowly but surely, they’re starting to look like a real baby.

It’s also around the 7th or 8th week that your baby starts to develop into a girl or boy.

If they’re biologically male, a gene will trigger the development of testes around this time.

Otherwise, your baby develops as a female.

And the tail? That’s almost gone by 8 weeks.


Pregnancy symptoms at 8 weeks

Your baby is going through a lot of changes, but what about you?

Can you show at 8 weeks pregnant?

And what other 8 weeks pregnant developments can you expect?

The truth is, an 8 weeks pregnant belly looks different for everyone.

Some mamas begin to show, but others won’t for a while.

It’ll still take another few weeks before you start to really look pregnant.

Are you wondering, what size is my uterus at 8 weeks?

Well, it’s gone from its usual size of a fist to about a large grapefruit.

Chances are, there are other things you’re noticing about your body right now.

Some common 8 weeks pregnant symptoms include:

  • A metallic taste in your mouth
  • Headaches
  • Cramping (a little like period pains)
  • Feeling bloated
  • Mood swings
  • Unusual food cravings
  • Heightened sense of smell
  • A milky white discharge from your vagina
  • Light spotting (although you should see your doctor if you get more bleeding than this)
  • Thicker and shinier hair
  • Patches of darkened skin on your face (known as “chloasma faciei”)
  • Slightly swollen breasts
  • You may feel tired (unsurprising, given how much is going on inside you!)
  • You may need to hit the bathroom more than usual, as your womb pushes on your bladder. If you’re waking up in the night to pee, try to stay hydrated in the day but hold back on liquids in the evening.
  • You may have already experienced morning sickness, and some mamas find it fades around this point. Unfortunately, for others, this is when it begins. An estimated 75% of women experience morning sickness, though the cause isn’t known for sure. It could be due to the increased hormones in your body or the relaxation of muscles in your digestive system as they make room for your growing womb.

But even if you’re feeling rough, your baby feels just fine.

Can you have an ultrasound at 8 weeks pregnant?

If you’re not sure when you became pregnant, or previously experienced an ectopic pregnancy or a miscarriage, your doctor may recommend you get an early ultrasound.

An 8 weeks pregnant ultrasound can detect the baby’s heartbeat and help work out your baby’s age and due date.

What are the chances of miscarriage at 8 weeks?

Although the risk is still there (80% of miscarriages happen in the first trimester), the chances of miscarriage at 8 weeks are still pretty low – around 1.6% or less.

If you do suffer a pregnancy loss, many people find that reaching out to others can be a big help.

You’d be surprised at how many women share your experiences, and mutual support can make all the difference.

Pregnancy tips at 8 weeks

  • Get your sleep on: Growing a human is tiring work! Make sure you’re getting enough rest and sleep to keep yourself feeling energized.
  • Keep moving: Staying active is important for your health and the health of your baby. Whether it’s taking a prenatal yoga class or going for a walk, find ways to keep moving and stay active.
  • Keep up with those prenatal appointments: Your healthcare provider is there to make sure you and baby are healthy, so don’t skip those appointments! Plus, getting to hear baby’s heartbeat is always a special moment.

Whatever your experience of pregnancy at 8 weeks, it’s something you’ll only go through once with this baby.

It’s special ‒ and weird at times.

You’re doing amazing things, mama!
