Everything you need to know about week 22 of pregnancy

22nd week of pregnancy (22 weeks pregnant)

Welcome to the 22nd week of pregnancy – you are now well into your second trimester. Your baby continues to grow rapidly, noticeably increasing in size and weight, and is developing more and more personality. In the 22nd week of pregnancy, you are likely not only to feel the movements more intensely, but also to sense emotionally the little miracle growing inside you.

Your body continues to change: your baby bump becomes more prominent, your weight increases gradually, and typical pregnancy symptoms such as back pain or water retention may occur. At the same time, this is a phase in which many expectant mothers experience calm, energy and even the first taste-related cravings or food aversions – and the anticipation grows with each passing day.

Development of the baby in the 22nd week of pregnancy

In the 22nd week of pregnancy, your baby continues to grow in size, weight, and strength. The proportions are becoming more harmonious – compared to the first weeks, the body now looks almost like that of a newborn, just much more delicate. The movements are also getting stronger: kicks, stretches, and little turns can now be felt regularly.

The brain is constantly forming new neural connections – especially for the sensory organs. The sense of touch is particularly active at the moment: your baby is exploring their surroundings a little, playing with the umbilical cord and discovering themselves – with hands, fingers and toes. The sense of balance is also developing more and more.

This week, the various layers of the skin continue to develop, while the first fat tissue deposits are forming under the skin – important for temperature regulation and energy. The nasal mucous membrane begins to develop, and the first taste sensations are perceived via the tongue through the amniotic fluid.

The lungs are preparing for life outside the womb with breathing movements, even though your baby is, of course, still being supplied via the placenta – ready for the big wide world out there.

Your body in the 22nd week of pregnancy

Your baby bump continues to grow – in week 22 of pregnancy, the upper edge of your uterus can usually be felt clearly above your belly button. This also changes your posture: many women report a hollow back, back pain or tension in the lower back area.

Water retention (especially in the evenings), tiredness, or mild heartburn are also typical companions this week. Your metabolism is particularly active, which may cause your body temperature to be slightly elevated – this is completely normal and nothing to worry about.

Your body is now producing more and more fat, some of which is stored as fatty tissue to strengthen you for the time after birth. These energy reserves are especially important for milk production.

Treat yourself to regular breaks, drink enough water, and wear comfortable clothing. A warm bath or gentle exercise such as yoga will help you feel at ease. If you like, you can also take your first photos of your baby bump – as a loving keepsake of this special time.
