Probably not : It is actually not that easy to get HIV from having normal vaginal intercourse. Practice safe sex from now on, condoms save lives. The unfortunate psychology of the fear of being infected is sometimes worse than the infection, and called a conversion reaction. Seek care for this.

Highly unlikley: But hopefully you were also tested for a host of other stds at the same time. The lesson is universal barrier protection. With mono-like illness this could be one of many other diseases, like cmv, toxoplasma, and so on. Only a detailed work-up is likely to clear this up, but then you have to ask yourself if it will make a difference in your long-term health, particularly if you are now better.
