Hello
The following conditions are associated with heavy periods:
fibroids
endometriosis
pelvic inflammatory disease
polyps of the lining of the womb.
The commonest cause is a condition called dysfunctional uterine bleeding (DUB). This refers to heavy bleeding with no apparent explanation.
Painful heavy prolonged menses can be due to endometriosis or PID ,you should consult an Gynaecologist for further evaluation to rule out these.
