Anal Sex & Yeast Infection HELP!!!

Hi there,

I had anal sex for the first time a few days ago for the first time, and my boyfriend wore a conform while we were doing it. And than we grinded & he was still wearing the condom that was up my ass.I know this was honestly dumb. I got carried away and didn’t think in the moment.

Yesterday I started having a lot of inching in my vagina, and there was some white stuff that came out. It was honestly really uncomfortable.

Today I peed and felt a burning sensation. Is this a yeast infection? And did I get it from grinding after anal?

Also if it is a yeast infection, how do I best treat it & how long does it take to go away?

I ordered some 7-Day Monstat & some probiotics for it. Will this clear up on its own?

Thanks
