Hello and welcome to health care magic, I understand your problem. This is not unusual. There are some local hormones called prostaglandins that are released during periods. They act on the uterus to produce contractions as well as cause shedding of the uterine lining as periods. However they may act on adjacent organs like urinary bladder and the intestines to irritate them. This leads to such symptoms. It cannot be predicted if these symptoms will recur. You will have to watch for the next few cycles to understand if there is a pattern. Most of the times the symptoms can be controlled by simple drugs like aspirin that inhibit these hormones and decrease effects. Oral contraceptives are also found to be beneficial. Regular exercise of the abdominal and pelvic muscles also helps control symptoms and is most effective. Hope this satisfies your query. Thanks for using HCM. Feel free to ask any more questions that you may have. Dr Madhuri Bagde Consultant Obstetrician and Gynecologist
