At 38 weeks of pregnancy, a hardening of the belly and painful sensations indicate that this phenomenon is caused by contractions of the uterus. If the contractions are regular, the baby will be born soon.

During this period, it is necessary to always check the fetal movements and the changes of the fetal heartbeat.
