Thanks for the query to H.C.M. Forum.
As you have taken treatment for gram +ve & -ve and also for pseudomonas
Vaginal ( cervical ) discharge is still as such. Pelvic inflammatory disease
is very serious .
You are taking treatment for symptoms , root cause of disease is still not found.
Consult a Gnaecologist and get blood culture
and drug sensitivity test for exact medicine.
Get well soon.
