Your condition is perhaps metropathia hemorrhagica, an abnormal bleeding pattern triggered by abnormal hormonal
levels in the body. If your blood tests, thyroid
profile, diagnostic curettage, hysterosalpingography
test, culdoscopy and vaginal and cervical cytology are all normal, you may be put on symptomatic and supportive treatment and if there is no use, if your child bearing function is over, you may go for a hysterectomy
. Please get further suggestions from your doctor. Good luck.
