TMI..Discharge and other signs.. UTI?

For a while know I've been having frequent urination (looks like there is white floaty things in it), pelvic cramping, green discharge(sometimes it's thick and creamy and others it's clumpy and sticky), bad odour, painful intercourse.. Any ideas? Possibly pelvic inflammatory disease? I have had a cervical procedure done improperly so I could have developed infection. My doctor has done a pap and Swab and said both were good.. Won't do anything extensive like ultrasound, pelvic examination, blood work etc.. Getting SO sick of this.
