First of all, you aren't exhibiting symptoms of HIV so don't worry about that.
However, anal sex is a very high risk activity...but you were using a condom so that significantly lowers your risk. You CAN get HIV from oral sex, but it is a lot less likely to get it that way than to get it by vaginal or anal sex.
Long story short, yes it is possible that you have HIV. But, there is also a strong possibility that you don't. Wait 3 months and go have a test. I hope you come back negative and that you make better decisions in the future
