How does ones body react if it's been infected by HIV/AIDS?

This is the wrong kind of site for this question. We would be re-writing huge amounts of information already on the internet. Just research HIV.

Plus, we don't know if you are 'just asking' or if you fear that you have been infected. If you have fears, you of course go to a clinic and get tested, possibly more than once. Please do not sit around worrying about every little symptom. And don't play Russian roulette with your body in the future. Know all about sexual diseases and how to prevent them before having sex, and know your partner well.

It will often go for months or years with no signs what so ever. If there is reason to be concerned, a test should be done
