Patient's question:
NoDoctor's answer:
The contractions of the uterus during labor are regular. In the initial stage, the interval is approximately every 10 minutes, and the pregnant woman feels intermittent abdominal pain. Subsequently, the duration of the pain gradually increases to 40 seconds to 60 seconds. The intensity also increases, and the interval shortens to about 3 to 5 minutes. When uterine contractions cause abdominal pain, the lower abdomen feels very hard.
