Yes for your own peace of mind, wait three months. Keep busy during those three months. If it is still necessary for you to go through the test after three months, then get tested.
Even if I tell your chances are you don't have HIV, you still have to go with what you think within.
Don't think you have no strength to go through this. As Nelson Mandela said, "Your biggest fear is not that you are inadequate, your biggest fear is that you are powerful beyond measure..."
Yes you are powerful. You can do this to clear your mind. Your mind is very important. Keep it calm.
All the best to you.
Always
