This is because during menstruation, women’s pelvis and uterus will become congested to varying degrees, stimulating the bladder and causing frequent urination, which will gradually disappear with the end of menstruation. However, women should also pay attention to the fact that if frequent urination occurs before menstruation, accompanied by urinary urgency and painful urination, they should consider whether there is a urinary tract infection, and they should go to the hospital for a routine urine examination in time. This is a very good idea to take antibiotics such as ciprofloxacin, norfloxacin, amoxicillin, etc. under the guidance of a doctor, and to drink more warm water at the same time.
