Also forgot to add I have recently developed a ucler or cancer sore on my lip
HIV does not spontaneously appear out of thin air. If she is HIV negative then there's no way you could be infected by her. The only way you would have a risk is if you were exposed to someone who is HIV positive.
Your girlfriend is not an unknown person or a risky individual. She tested negative and as long as she hasn't cheated, that means she doesn't have HIV. As Chima says, you can only get hiv from an HIV + partner. People get sick all the time and it is that time of year where you see it happening more. If you have an ulcer on your lip, maybe you have herpes simplex 1 which is oral herpes. About 80% of the population have it (including kids). But I would not suspect HIV if in a monogamous relationship with a woman who recently tested.
Understood - thank you ! Okay last question.
For ARS- typically, do all symptoms come at once ?
Or symptoms continue to develop?
