Hi ! You have not mentioned if you are also running fever
or not. Also if you are sexually active, then an unnoticed pregnancy
and a partial miscarriage
might have to be ruled out. At home you can go for a urine preg-test. If this is not conclusive, you can discuss with your family physician and go for serum HCG
test and an ultrasound
abdomen. If all these things are clear, then you can go for a culture and sensitivity test of the discharge and then for appropriate antibiotics. If everything is normal and the problem persists, then you have to visit a gynaecologist, who may advise you some medications, and a dilatation and curettage, which possibly will relieve you of your condition.
Wishing you an early revcovery.
