Congratulations! You have now entered the second
trimester of your pregnancy. This means that the risk of
miscarriage and deformity decreases.
The fetus in week 12
The fetus is now 10 weeks old. It is now 6–7
centimeters long and weighs 10–20 grams.

is now developing at full speed. It is already formed in
the arms and legs as well as around the fetal head. Over
the course of next week, the entire skeleton will be
In week 12, the fetus's head is half the body length
and the nose, oral cavity, tongue and tooth abutment
where the milk teeth are to come out are already in

Good tips for week 12
Walking and plenty of fluid can help with headaches.
For those who have problems with dizziness, for example,
when you get up quickly, there are two tips to take:
Change your posture slowly and lie with your legs high
(above heart height).
If the pain becomes an obstacle in everyday life, you
can consult your doctor.
