You might start to feel a slight baby bump and your baby is officially a fetus this week! There’s a lot of wonderful things taking place within your body right now so let’s take a look at what to expect at 10 weeks pregnant.

How big is my baby at 10 weeks pregnant?

Your baby is growing rapidly now and should measure 3.1cm and 4.2cm and weigh around 5.7g. That is about the same size as a grape!

Your baby’s development at 10 weeks

In week 10 of pregnancy, your baby will be looking a lot more like a tiny human, only with a big oversized head! Your baby’s head is half the size of its whole body this week as it accommodates rapid brain growth. This will become more proportional over the next few weeks.

Your baby’s bones, cartilage, and joints are all starting to form this week and they will be able to move their arms around, although you will not be able to feel them just yet.

Week 10 should also see dinky tooth buds starting to form under the gums and your baby’s kidneys are now producing urine!

Changes in your body at ten weeks pregnant

At 10 weeks pregnant, symptoms can vary drastically from mum to mum.

Coping with fatigue

You are likely to feel a little fatigued at this early stage of your pregnancy.

Although getting in some much-needed rest is important, it can also feel good to participate in some very gentle exercise. This will encourage the release of endorphins that can help you sleep and manage any hormonal mood swings you may be facing.

Nausea and sickness

If you are dealing with nausea and trying to cope with morning sickness it’s important to try and keep your food down and to stay well hydrated.

You may also experience dizziness. This is often caused by dips in your blood pressure or from a low amount of sugar in your blood. If you suffer from dizziness, try to find somewhere to sit down as quickly as possible. Many mums find relief through a healthy snack to help replenish sugar in the blood.

Always speak to your GP or midwife if you are experiencing frequent dizzy spells.


Boobs and veins

Swollen and sensitive boobs are very common in week 10. This happens when the pregnancy hormone progesterone forces your milk ducts into overdrive. Breast sensitivity should slow down in your second trimester. If your boobs are swelling up or sore, you might want to consider some looser bras.

You may also notice some bodybuilder looking veins appear this week. They won’t be as visible as varicose veins, but you might start to see them all over your body, especially around your breasts and abdomen. In later trimesters these veins can appear on your hands and feet.

Don’t panic because this is very normal on your breasts and around your lower abdomen as your body moves blood around.

Back pain relief

It is very common to be faced with lower back pain in your first trimester. Your uterus is expanding and your hormones are in overdrive so some of your poor muscles might be finding it hard adjusting to these changes.

Now is definitely a good time to get those flats out and make sure you treat yourself to a good long soak in the bath if the pain is becoming unbearable.

Increasing hormones

Your nearest and dearest might be commenting on your mood swings this week.

First-trimester pregnancy hormones can make women go a bit bonkers but you do have a get out of jail card for any random explosions or teary outbursts.

Hormonal changes can also be the cause of constipation. If you find yourself struggling to pass stools, try to eat lots of fiber (raspberries and apricots are great) and make sure you keep drinking lots of water.

Pregnancy glow

It’s not all bad news in week 10 of pregnancy.

You might notice people start to comment on your wonderful youthful radiant glow. In fact, lots of mothers can sniff out a yet to be announced pregnancy because that wonderful pregnancy glow is unmissable to a trained eye.

A pregnancy glow is caused by the hormones hCG and progesterone, which can give your skin a shiny healthy look because they increase the number of oil glands on your face.

Prenatal testing

Prenatal testing, or screening, are terms used for the types of tests your doctor might recommend for you during pregnancy. Your doctor has probably already discussed these screenings with you at your first prenatal appointment.

Weeks 10 through to 13 are the main window for prenatal testing. The screenings tend to be noninvasive and are optional.

First-trimester prenatal screening tests usually involve an ultrasound and blood test. They can help determine whether a baby may have certain health conditions or chromosomal abnormalities, such as Down syndrome.

These screenings provide only a possibility (or risk) that a certain condition exists. They don’t guarantee that a baby will have predetermined conditions or chromosomal abnormalities.

If you decide with your GP to take these screenings, and the results are positive, then your GP may recommend further, more evasive, diagnostic tests. Evasive tests can help provide definite answers for you and your doctor.

Things you should be doing at 10 weeks pregnant

Here is a list of some of the important things you should be doing this week:

  • Keep hydrated and drink lots of water.
  • Keep the gentle exercising going.
  • Now is a good time to start looking for those larger bras.
  • Dr. Google is a great resource for general parenting support but try not to self-diagnose concerns. If something is worrying you, however small it may seem, contact your GP or midwife.
  • Speak to your GP or midwife about prenatal testing
  • It’s never too early to start thinking about baby names.
