Hello, Thanks for letting us know your health concern. During the initial years of menstruation, it is quite common to experience abnormal menstrual pattern as the body adjusts to the new hormone levels. Your doctor is likely to do a general check up, a local examination and if necessary would go for a pelvic exam. If you are a virgin, a per rectal exam is preferred. Blood counts and urinalysis and a sonogram of the pelvis are suggested. You need to improve your nutritional status and hormones may be need ed to stabilize your cycles. Hope this helps.
