During pregnancy, it is normal to go to the toilet at night, if there is no painful urination and no discomfort when you urinate. After pregnancy, the fetus will increase in size and the uterus will also increase in size, which will squeeze the nearby organs and squeeze the bladder, resulting in a decrease in the capacity of the bladder and the phenomenon of frequent urination.
