hi, i had a protected vaginal sex. nothing else! with a sex worker 25 days ago. 10 days later i had a diarrhea which lasts 2 weeks and then became constipation with some pain and complications. a little fiver at night for 3 days ,night sweat sometimes. lost of appetite and lost weight .i m sure that the condom didn t break, because when i was done i took it home and i tested it by putting a hot water in it and i checked it very well no water coming out. now in my 25th day i feel better .could be this a hiv infection? please help.
