Since the day I started getting my periods I have a regular cycle of 30 days and is about 10 years. But I had painfull bleeding from the start. As d pain was intolerable and as it affected my work I went to a doctor last month. She gave me Duoluton L for 21 days. Now I got my periods and I didn't get the pain. Should I continue those tablets? Will I gain weight? I am going to get married by December....nd will it affect ovulation?
