A hard tummy at 34 weeks is generally considered to be a pseudo contraction, because in late pregnancy, the uterus becomes sensitive due to the increase of contractin receptors in the uterus, and the slightest stimulation will cause uterine contractions. However, if the hardness of the stomach is persistent or the contractions are more frequent, accompanied by increased secretions, or even develop into a painful feeling of falling stomach, you should go to the hospital for a timely examination to exclude the hardness of the stomach caused by placental abruption. If the contractions are frequent and cause preterm labor, it is recommended that the pregnant woman should pay attention to rest. If there are no maternal-fetal complications, you can suppress contractions without contraction inhibitors, and you should go with the flow of nature without intervention, and you can continue to monitor the situation of mother and fetus.
