Yeast infection?

The last couple of days my one labia not both has been sure itchy to where I’m rubbing it raw and my pee hole is itchy. I took amoxicillin because I had swollen lymph nodes and then my boyfriend and I had sex he wanted to anal and I was super drunk and he put it back in my vagina not thinking about a uti and he used lotion as lube without me know but as soon as i finished the amoxicillin I got a uti. Shortly after I started getting the itching feeling and I’ve used itching cream on the skin and stuff for yeast infection and nothings making it stop… the doctors can’t get me in till the end of the week. Has anyone experienced this before? I have never had this issue before.
