Hi,
Thanks for posting in HCM.
I understand your concern.
From your description, it appears that you had
non-penetrative sex by just contact of penis with vagina and
oral sex after wearing condom.
Under such a circumstance,
HIV can only be transmitted if your penis has come in contact with her vaginal secretions. Otherwise, contact of HIV seems to be a remote possibility.
CMIA tests are done to look for both
antibodies and P24 antigens during the window period. The window period for the CMIA test is 3-4 weeks. Since it is negative on 35th and 55th day, your HIV status is negative.
If you are doubtful with the result, you can get HIV status tested as per the recommendations after 6 months.
Hope the information provided would be helpful.
All the best.
