HIV Symptoms. Due to vit-d deficiency.

I had a unprotected sex with my friend who is married and she claims that she dont have HIV and also have healthy life, it happened 17 days back and it happened twice, before that i have physical relation with three other girls and three of them don't have HIV, from 3 weeks i have been experiencing light body pains (shoulder, hands and below knees) but these are not severe and not present all the day, also head ache some times , little body temperature not all the time and dry cough which is not very much and also not continuous, but they are coming and going, i also got tested HIV I & II and it came negative(not reactive) and another test for Vitamin D is also done which and results are very bad i have only 11% on vit-D(deficiency). Before that i fasted for 40 days and ate once a day, but these symptoms are coming and going. Even Doctor said you are not infected with HIV after the reports. Kindly Suggest if i should get tested again or are these symptoms due to Vit-D Deficiency .
