Hello,
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. Get it evaluated from your gynecologist to confirm the diagnosis.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
You could have a hormone imbalance. You really need to see an ob/gyn right away as you could now be anemic with bleeding for 8 weeks. Call your doctor and set up an appointment.
