Abnormal Discharge

Hope

I’ve been experiencing excessive discharge for the last year or so. It’s greenish/yellow/cream in color and smells like medicine. Ive also have had a lot of recurring Utis this year. I’ve mentioned to my Gynoand he prescribed me to take 1 antibiotic pill after sex to prevent the uti and rephresh probiotic for the discharge. The Utis have gotten better but I am still having a lot of discharge. What could it be ?!
