What’s happening to the mother?

Your body will gradually begin to prepare for childbirth at the end of this period through more frequent and clearer contractions in the uterus. These start at the top of the abdomen and spread throughout the uterus before subsiding. They normally last about 30 seconds.

These are known as Braxton Hicks contractions. At first, Braxton Hicks contractions may feel like weak menstrual pain, but they can gradually become increasingly uncomfortable. They should not be painful.

If you have given birth before, you may feel Braxton Hicks contractions earlier in your pregnancy and often perceive them as being stronger and more intense.

It can sometimes be difficult to tell Braxton Hicks contractions from proper contractions. Braxton Hicks contractions normally pass quickly and can change if you lie down, change position or move. They are not regular and rarely increase in intensity.

Development of the fetus

The baby’s internal organs are now fully developed, with the exception of the lungs, which take a little longer to mature. The baby therefore does regular breathing exercises.

The baby will be around 45 centimetres long and weigh between 2,200 and 2,600 grams.

Antenatal checks and tests

All pregnant women are entitled to antenatal care. The service is free and intended to ensure that you receive the best possible care and guidance during and after your pregnancy.
