You did not have any risk to begin with. Anxiety can cause other symptoms to pop up, which you might then mistake for HIV. Testing is not warranted in your case, but you if you overtly anxious, you could just go get a fourth generation test after 4 weeks to allay your unwarranted fears. Thank you.
You used a condom therefore you had no risk. Oral sex is not considered a risk, either with or without a condom. You're fine and have no reason to freak out. Testing is obviously not required seeing as how you had no risk.
