Pregnant in week 10
In week 10 your baby is the size of a kumquat. The nails start growing, the joints work so the arms and legs can bend, and from this week the NIPT blood test can be taken if you want early genetic insight.
Your baby in week 10
Your baby measures around 3 centimetres and weighs about 20 grams. The main organs have formed and are now beginning to work: the kidneys produce urine, the stomach makes digestive juices, and the liver makes blood cells.
Small nails begin to grow on the fingers and toes, and the joints in the elbows and knees work, so your baby can bend its arms and legs. The movements have become smoother, even though you still can't feel them.
The head is still large, but the body slowly straightens. Tooth buds form inside the jaw, and the fine bones begin to harden from cartilage into bone.
Your body and symptoms in week 10
You are now close to the end of the most symptom-heavy trimester. For some the nausea has begun to lift, while others still find it hard – both are normal.
The uterus takes up more room in the pelvis, and although the bump can hardly be seen yet, you may feel rounder. Veins can become more visible on your breasts and legs as your blood volume rises.
If you want NIPT, now is when the test can be taken. It analyses your baby's DNA in your bloodstream and gives a very precise answer on Down syndrome among other things. Contact us to hear more about your options.
Good advice for week 10
Decide on prenatal testing
NIPT can be taken from week 10, and the nuchal scan is offered from week 11+4.
Book the double test
The double test is the blood sample that goes with the nuchal scan. It must be taken at least a week before the scan so the result is ready to be combined with the nuchal fold measurement.
Care for your gums
Pregnancy hormones soften the gums, so they bleed and inflame more easily. Good brushing and a check-up at the dentist prevent problems.
Start iron this week
The Danish Health Authority recommends 40-50 mg of iron daily from week 10 and for the rest of the pregnancy. If nausea makes it hard, you can wait – but start by week 18 at the latest.
Keep up the vitamins
Folic acid is recommended until week 12 and vitamin D all the way. Many switch to a standard pregnancy vitamin that covers both.
Move at a pace you can manage
Regular, gentle exercise strengthens circulation and mood. If you have nausea, choose the times of day when you feel best.

Frequently asked questions in week 10
What is NIPT?
NIPT is a blood test that analyses small pieces of your baby's DNA in your blood. It is very precise for chromosomal conditions such as Down syndrome and can be taken from week 10.
Is NIPT the same as the nuchal scan?
No. The nuchal scan is a risk calculation from a measurement and a blood test, while NIPT analyses your baby's own DNA and is more precise. The two can complement each other.
Can I feel the baby in week 10?
No, not yet. Your baby moves but is too small. The first movements are typically felt between weeks 16 and 22.
