There is no need to worry about the strong fetal movement at 40 weeks of pregnancy always wanting to pee, and no special treatment is needed. You can change your position appropriately and avoid keeping the same position for a long time.
Under normal circumstances, urine is stored in the bladder to a certain amount, and is discharged after producing an obvious desire to urinate, while the bladder and the uterus are neighboring organs located in the front of the uterus. After pregnancy, the fetus grows in the uterus, and the pressure exerted by the uterus on the bladder gradually increases. In the second trimester, when fetal movement occurs, the pressure exerted by the uterus on the bladder becomes more pronounced, which in turn produces a noticeable urge to urinate.
