Hi welcome to health care magic forum. Continuous bulky and pain full period suggests that there may be some infection. Other causes being anaemia
, harmonal imbalance, etc.
I advise you to consult a gynaecologist for diagnosis and treatment. You need to have P.V.examination for confermation of the disease.
Besides i advise you some diet recommendations for correction of anaemia, and general health problems. Take more of green leafy vegetables, pulses, sprouts, egg, fish, chicken, meat, milk, fruits, juices, and dry fruits.
Wishing for a quick recovery and thanks for calling.
