Under normal circumstances, frequent urination will not occur in early pregnancy. Early pregnancy reactions such as anorexia, nausea, vomiting and breast tenderness may occur with the rise of progesterone and HCG in the body in early pregnancy, but in general, frequent urination will not occur. If the symptom of frequent urination appears in early pregnancy, it may be due to pregnancy reaction that leads to reduced water consumption, etc., which triggers urinary tract infection. With the increase of pregnancy time, the symptom of frequent urination may appear at 50-90 days of pregnancy because of the enlarged uterus pressing on the bladder, and the uterus leaps out of the pelvis after three months, and the symptom of frequent urination will be reduced naturally. If a woman has symptoms of frequent urination in early pregnancy, she should drink more water, pay attention to perineal cleanliness and hygiene, and observe whether the symptoms improve; if they don’t, she should go to the hospital for routine urine tests to determine whether the urinary tract infection is the cause.
