Vaginal cut infection??

Maddy

So a little less than a week ago I got a random fever that lasted about a day or so along with swollen lymphnodes. I thought I had a UTI so I went in to my doctor and she noticed I had a tiny scrape and 2-3 very small white blisters on my vaginal area, right below the scrape. I got it tested but don’t find out the results till Monday. My boyfriend and I don’t have penetrative sex and he’s been tested and is clean but is it possible that I have an STD? Or could it just be that the cut got infected which caused my fever and swollen lymphnodes??
