Hello, A slight alteration in the menstrual cycle is quite common with microlut. Nothing much to worry and your periods will return to normal pattern in a couple of weeks. If the periods are persistently irregular, you can consult a gynecologist and get evaluated to rule out conditions like PCOS. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Shinas Hussain, General & Family Physician
