Baby development this week
At 10 weeks pregnant, your baby is no longer usually described as an embryo. They are now a foetus, which means the main early body structures are in place and will continue to grow and mature over the weeks ahead.
Your baby’s head is still large compared with the rest of the body, but the face is becoming more defined. The eyelids are developing, the tongue is formed, and the tiny tooth buds are already in place beneath the gums.
The arms are longer now and can bend at the elbows. The legs are developing too, and your baby can make small movements, although you will not feel them yet. Those first noticeable flutters are usually still several weeks away.
The heart is still developing, but some of the earliest stages of heart formation are now behind your baby. The tail-like structure seen earlier in development is also disappearing, helping the body look more recognisably human.
What's happening to your body
At 10 weeks pregnant, your uterus is continuing to grow. It may be around the size of a small orange, although you may still not have an obvious bump.
First-trimester symptoms can still be very present. You may be dealing with nausea, tiredness, sore breasts, bloating, constipation, frequent weeing, food aversions or mood changes. Some people start to feel a little better soon; others have a few more difficult weeks before symptoms ease.
Pregnancy hormones can also affect your joints and ligaments, which is one reason to keep movement smooth and controlled rather than suddenly pushing into intense new exercise. Staying active in pregnancy is encouraged, but this is not the time to suddenly push into intense new exercise. Choose movement that feels manageable, warm up properly, avoid overheating, and stop if you feel dizzy, faint, unusually short of breath, or in pain.
You do not need to “train for birth” this week. Gentle walking, stretching, swimming, pregnancy yoga, or continuing familiar exercise at a comfortable level can all be useful if you feel well enough.
How you might be feeling
Reaching Week 10 can feel like a small milestone. You are in double figures, your first scan may be getting closer, and the pregnancy may be starting to feel a little more real.
That does not mean you have to feel calm. You may still be anxious, especially if you are waiting for a scan or have had a difficult early pregnancy experience before. You might also feel fed up if sickness and tiredness are still affecting your normal life.
This is also a stage where secrecy can become tiring. You may be hiding symptoms at work, making excuses socially, or wondering when and how to tell people.
If your mood feels persistently low, panicky, or unlike you, speak to your GP, midwife or maternity service. You do not need to wait until later in pregnancy to ask for emotional support.
Things to think about this week
If your booking appointment or dating scan is coming up, start noting down any questions you want to ask. You may want to ask about screening tests, scan timing, local maternity services, exercise, symptoms, medicines, or anything that is worrying you.
Useful things to line up:
- keep taking folic acid until 12 weeks, unless you have been advised otherwise
- continue vitamin D if recommended or included in your pregnancy supplement
- think about whether you want someone with you at your scan
- choose gentle, familiar exercise if you feel well enough
- check that any workout classes or sports are suitable for pregnancy
- plan simple meals and snacks if nausea is still making food difficult
- think about what support would help if symptoms are affecting work or home life
Try not to overload yourself with baby shopping yet. This week is more about looking after yourself, staying comfortable, and preparing gently for the next stage.
