Your current presentation could be related to an infection, fibroids in the uterus, polyps, endometriosis
, endomterial hyperplasia
The causes are numerous. So I would advise you to visit a doctor and get yourself checked (urine as well as a sepculum examonation or a transvainal ultrasound (TVS).
But, your old complaints of a clumpy white discharge matches that of bacterial vaginosis
, yeast infection, etc. If you are still experiencing these, then please report them to your doctor as well.
Hope this helps.
