The feeling of a falling stomach at 32 weeks of pregnancy is due to the middle and late stages of pregnancy, when the fetus is developing rapidly and the uterus is growing rapidly and becoming larger. The uterus can squeeze any surrounding tissues, touching the rib cage upward, squeezing the bladder or reaching the pubic symphysis downward, which will cause the uterus to feel swollen and painful, which is a normal physiological phenomenon. In addition, an enlarged uterus can also cause pain due to the tightening of the ligaments around the uterus. In addition to the physiological pain, the contraction of the uterus in the middle and late stages of pregnancy may also cause pain in the lower part of the stomach. If the pain is not relieved by self-treatment and gets progressively worse, hospital consultation is recommended, unless other diseases are involved.
