Hi,
Welcome to HCM.
Thanks for posting your query.
The test that you underwent seems to an antibody detection rapid test. All HIV tests available in the market are highly reliable up to the extent of 97% and above. Window period for HIV test is 6-8 weeks (and 12 weeks at the maximum) after the risky contact. You had your nonreactive test 14 weeks after the exposure.(7 weeks test has little value as it had not crossed widow period). So your nonreactive test is highly reliable and you are free from HIV and no further test is necessary for you.
