6 Weeks Pregnant – Your Body and Your Baby

6 weeks pregnant

At 6 weeks pregnant, you may notice that you need to pee more often — especially in the middle of the night! This will ease in the coming weeks, only to return with a vengeance later in your pregnancy. You will also be feeling a little more fatigued than normal.

Your body is making a baby, which is a mammoth effort. Make sure you don’t push yourself – listen to your body when it’s telling you to rest.


6 Weeks Pregnant – Your Body

You may have already started feeling the signs of pregnancy:

  • Nausea
  • Heartburn
  • Bloating
  • Constipation
  • Increased appetite
  • Occasional backache / lower backache
  • Extreme fatigue
  • Shortness of breath
  • Over emotional, lots of crying, anxiety
  • Sore breasts/sore nipples
  • Light headedness/dizziness
  • Sensitivity to smells
  • Things taste “different”
  • Wondering if I am actually pregnant!

Please note that everyone is different, and you may have some, all or none of these at this stage of pregnancy.

There’s a very good chance that morning sickness has paid you a visit — it affects around 80-90% of pregnant women. Don’t get mislead by the name, ‘morning sickness’, because it often lasts all day. No one is sure what causes morning sickness, but possible causes are pregnancy hormones, blood pressure changes, and changes in carbohydrate metabolism. Morning sickness usually resolves around 12 -14 weeks of pregnancy. Studies have shown that women who have moderate morning sickness are 70% less likely to miscarry.

About 0.3 – 2% of women develop hyperemesis gravidarum, which is severe vomiting in pregnancy. Hyperemesis gravidarum is diagnosed when you are vomiting several times a day, are unable to eat and drink without vomiting, and are losing weigh.t. It can mean a short stay in hospital for rehydration, and requires some practical and emotional support for mum-to-be. For more information, read our article here.

Are Cramps Normal At 6 Weeks Pregnant?

So, implantation has certainly passed by now, is it normal to still experience cramping? While your baby is still quite tiny, your uterus is already beginning to change.

As the uterus prepares to make room for a growing baby, it begins to expand. This slow growth can cause cramping for many mums-to-be.

Cramping in early pregnancy is typically considered a normal symptom. Cramping without any bleeding, is usually not a concern.

Anytime you experience bleeding, though it’s not always a concern, it’s important to report the bleeding and accompanying symptoms to your midwife or doctor. Any severe cramping, especially localized pain, should be also be reported, with or without bleeding.

Generally, cramping can be a normal symptom during early pregnancy. You can read more in Bellybelly article Cramps During Pregnancy – What You Need To Know

6 Weeks Pregnant – Your Baby

Your baby already has a bloodstream. The heart, which is no bigger than a poppy seed, is not yet fully formed — it only has two chambers instead of the usual four. But these will soon develop. The baby’s heart beats at around 150 beats per minute, which is around twice the rate of an adult!

If you could look closely, you would see four little buds, which will soon become arms and legs. On the sides of your baby’s head, eyes have started to develop. Over the following weeks, the eyes will move into the correct position. Nose, mouth and ears are also taking shape and will form your baby’s face. The lungs are just starting to appear, along with the kidneys and intestines. Your baby’s spine has started to form.

At 6 weeks pregnant, your baby starts to look a little like a jellybean and is about 4-5mm long – the size of a grain of rice! Babies at this age are measured from crown to rump (i.e. head to bottom), so the measurement excludes his or her legs.
