Week 9 of pregnancy
The baby's face is slowly forming. The eyes are bigger and more obvious, and have some colour (pigment) in them. There's a mouth and a tongue with tiny taste buds.
The hands and feet are developing – ridges identify where the fingers and toes will be, although they haven't separated out yet. The major internal organs, such as the heart, brain, lungs, kidneys and gut, continue developing.
At 9 weeks of pregnancy, the baby has grown to about 22mm long from head to bottom.
Week 10 of pregnancy
The ears are starting to develop on the sides of your baby's head, and the ear canals are forming inside the head.
If you could look at your baby's face, you would be able to see an upper lip and two tiny nostrils in the nose. The jawbones are developing and already contain all the future milk teeth.
The heart is now fully formed. It beats 180 times a minute – that's two to three times faster than your own heart.
The baby is making small, jerky movements that can be seen on an ultrasound scan.
Week 11 of pregnancy
The baby grows quickly and the placenta is rapidly developing – it'll be fully formed at about 12 weeks.
The bones of the face are formed now. The eyelids are closed and won't open for a few months yet.
The ear buds developing on the sides of your baby's head look more like ears as they grow.
Your baby's head makes up one-third of its length, but the body is growing fast – it's straightening, and the fingers and toes are separating. There are fingernails.
Week 12 of pregnancy
Just 12 weeks after your last period, the foetus is fully formed. All the organs, muscles, limbs and bones are in place, and the sex organs are well developed. From now on, the baby has to grow and mature.
It's too early for you to be able to feel the baby's movements yet, although she or he will be moving quite a bit.
Your baby's skeleton is made of tissue called cartilage and, around now, this starts to develop into hard bone.
Your Body at 9-12 Weeks Pregnant
During this time your breasts will have got bigger, so consider wearing a supportive bra. You may also find that your emotions vary – you feel happy one moment and sad the next.
Don't worry – these feelings are normal and should settle down. Find out more about feelings, worries and relationships in pregnancy.
If you haven't seen your midwife yet, contact your doctor or maternity team for your booking appointment and to start your antenatal care.
This appointment should take place by the time you're 12 weeks pregnant. You will be offered your first ultrasound scan when you're between 8 and 14 weeks pregnant, but this can vary depending on where you live.
Some women experience bleeding in early pregnancy. Find out the possible causes of vaginal bleeding in pregnancy and what to do if it happens.
