Hello Dr,
16 weeks before i had a low risk of exposure to HIV, i had sex with a prostitute with 2 condoms, apart from that she sucked my penis for 5sec only and i fingered her for 10sec, after 2weeks i had loss of appetite, vomiting like feeling in morning, after 16weeks i vomited blood(i drink daily for last 10months) i tested both rapid and Elisa after 16weeks which came negative. Should i retest after 6months i am worried a bit please help me..
