Your baby is almost fully developed. Except that if he was born now, he would not be able to keep himself warm. Neither does he have enough resistance yet.
The downy hair on the baby´s body is starting to shed, disappearing in the amniotic fluid. Because the baby regularly swallows the amniotic fluid, these tiny hairs get into his intestines. This doesn't matter; in fact it is actually good for him as it helps train his intestines.
There is a fairly good chance that your baby is already in a head-down position, but don’t worry if this is not the case. He will still have enough room to turn for at least another two weeks.
Your midwife or obstetrician will usually take another blood sample around now. This is to test whether your blood is producing antibodies against your baby's blood. This could happen if you are rhesus negative and your baby is rhesus positive, for instance. The baby could develop anaemia if the antibodies reach him through the umbilical cord. You may be given an injection to prevent any further production of antibodies. Luckily, this only happens very rarely.
