Hi and thanks for the query, It might be of interest for you to get consulted. Do you have any headaches? Or any breast discharge? these could be signs of increased prolactine levels that could interfere with normal menses. Screening for thyroid disease could also be of utmost importance. A clinical examination of the abdomen could be very appropriate. The characteristics of your very first menses should be known. How long did you start experiencing abnormalities in your menses after you had your first menses? If it started right from the very start, diseases like humen retraction, non septate hymen and an imperforate and incompletely perforate hymen should be considered. an abdominal ultrasound could help in ascertaining the presence or absence of clot collection in the pelvis. Painful urination could either be as a result of a mass/pressure effect on the bladder or due to a urinary tract infection. A urinalysis and urine culture could give a clearer picture. I suggest you book an appointment with your gynecologist for proper clinical examination and management. Thanks and best regards, Luchuo, MD.
