The condition of always going to the toilet in the 5th month of pregnancy may be due to overactive bladder syndrome caused by the enlarged uterus pressing on the bladder, or it may be a symptom caused by urinary tract infection due to low resistance, so the diagnosis should be clarified by urine routine and urine culture examination. If there is a urinary tract infection, you should choose some antibiotics with higher sensitivity and better safety, such as amoxicillin capsules, cefuroxime tablets, azithromycin tablets, and take oral treatment for 5-7 days, so that the symptoms can be effectively improved after controlling the urinary tract infection. If the examination reveals no obvious inflammatory infection, it is likely that the uterus has enlarged and compressed the bladder, resulting in such symptoms. If this is the case, no special treatment is needed, and the symptoms will usually disappear as the pregnancy lengthens and the symptoms slowly adapt.
