Cold flu like symptoms? hiv?!

Ok so this total douchebag was my first and only guy I've ever had sex with. I only did it with him once, and at first he wasn't wearing a condom but I asked him to wear one so he did. Anyways, five days later I have a yeast infection, four weeks later I have this terrible flu, I've never had such a weird flu. But it lasts only for a week. So I'm scared what if maybe these hiv symptoms. I am going to the doc, I just wanna know what you guys think. I hear that these flu like symptoms last longer than a week, but please I wanna hear what you guys think.
