Tested ana positive what does that mean?

I've been feeling tired weak and sore for the last few weeks. I had some bloodwork done and the doctor said I was ana positive. She said to wait two weeks and if I was still feeling this way she refered me to a rhumatologist. She asked if there was a family history of lupus or rhumatoid arthritis etc (not that I know of). She didn't mention it and I was kind of nervous to bring it up but the first thing that came to mind when she said autoimmune was hiv. if that was a possibility would she have mentioned it? And is it a possibility? The copy of the blood test is all jargon to me. I've been pretty carefull but not knowing what it is has made me quite nervous. If anyone has any insight on positive ana test I would greatly appriciate it.
