Thank you for posting your query.
of your lip may be due to Herpes simplex
infection or may be due to your fear. Cold
symptoms may likely to everybody exposed to vial infection or Flu. Your bowl movements are also not very specific for HIV
HIV symptoms usually occur only after the immunity goes below a critical level that may take more than 5 years from the date of infection. Acute infection likely to occur earlier but difficult to recognize and fix the etiology as HIV.
So it is better for you to for an HIV antibody test 2-3 months after your suspected contact and get cleared the same. If you are very much you can go for HIV DNA PCR, which can reveal the infection at an earlier stage ,say, 3-4 weeks after the suspected contact.
If you are negative with these test you need not worry about the same.
