Needing advice

So I have been experiencing greenish/yellow CM but not a lot only little bit about a week before I get my period and there is no foul smell and it’s not itchy or hurts to pee and that’s it, I’ve gone to the doctors and they gave me a pap exam and it came back abnormal and I am to come back in 6 months. I’ve been looking it up and it comes back to BV or STI but I know it’s not a STI as I’ve been to the doctor twice this year. Any thoughts or info from someone that’s been through this.
