You seem to be having the symptoms of metrorrhagia(heavy periods
). Various factors causing it are endometriosis,ectopic pregnancy,hormone imbalance
,endometrial hyperplasia,polyps,use of IUD’s and depo shots, sexually transmitted diseases,PCOS and benign and malignant pathologies of the uterus.
I would suggest you to consult a gynecologist and get a pelvic examination and swab culture done to confirm the diagnosis. Treatment depends on the confirmation of diagnosis.
