How big is my baby at 12 weeks?
Your tiny baby is now a compact 6cm in length, and fully formed, although it is unlikely you would be able to get a reliable sexing at a scan just yet. They are moving around a lot at this stage, but you still won't be able to feel this for a while as they still have a lot of space to bob about in. Their eyelids remain fused shut at week 12 (they will open at around week 27), and their little wrists and elbows bend as they move around.
Facts to know about your baby in week 12
- By now, your baby is producing urine which is peed out into the surrounding amniotic fluid
- Your tiny baby is now fully formed and around 5.5cm
- Your baby's little wrists and elbows bend now as they move around
- Baby's finger nails and toe nails are forming
- As well as a developing skeleton, your baby's organs and intestines are now developing
You at 12 weeks pregnant
You are now in the last week of your first trimester – doesn't time fly? You might be putting morning sickness and extreme exhaustion behind you a bit now, although all those hormones could still be leaving you somewhat emotional! You are probably having lots of fun leafing through baby catalogues and mulling over nursery colour schemes, so now could be a good time to think about any changes you need to make to your home – you probably won't want decorators in, or having to make big decisions (or even do some light DIY yourself) late in pregnancy. You might also be finding it hard to resist a few sneaky purchases of unisex baby clothes now, too.
And if you've had your dating scan you are no doubt the very owner of a set of ultrasound images of your baby son or daughter!

What to think about in week 12
If you have an existing health condition you might be worrying about how you will manage it in pregnancy, even if it is something fairly common like asthma. Your GP and midwives will of course have given you advice on this from your earliest appointments, and checked that your medication was suitable for use in pregnancy, even so, do keep an eye on any changes at all in your health, and always flag any new or heightened symptoms up, no matter how small - you might find that for some health issues, your meds need tweaking or monitoring as your pregnancy evolves.
Signs and Symptoms
Even before you show real signs of a pregnancy bump, you can think you are showing as your belly bloats and later in the day your clothes feel tighter round the waistline. Hormones cause the abdominal bloating and can cause your digestion to slow down leading to indigestion, trapped wind and other embarrassing symptoms.
It’s annoying but this common early pregnancy symptom may still be plaguing you. The cause can be as simple as your body adjusting to such huge changes a pregnancy brings. You may find if you suffered from headaches normally, they have gotten worse during your pregnancy. Do bear in mind that if you were a big caffeine drinker before you were pregnant and have cut a lot out, it could be caffeine withdrawal causing your headache, but stick with it and find out about coping with headaches in pregnancy.
