The doctor that was on this site has left several months ago. I am the new community leader. I am not a doctor but am a clinical microbiologist. If you need help with HIV the HIV forum is still available and the STD site is available. The STD site and most of the other sites do not have doctors either.
I try not to answer questions about HIV since this is not the HIV forum but I can answer your question and if you want to also ask elsewhere you can. The 4th generation HIV test is very accurate and you can tell if you are positive 17 days after exposure so if you were negative after 17 weeks you are clear. You don't have to repeat unless you yourself are nervous but there is no reason to do it.
For Hepatitis B the window period is 45-160 days. So on the long end it is about 22.8 weeks.
For Hepatitis C the gold standard is anti HCV negative, HCV RNA test negative ALT liver enzymes negative. But the window period for the exposure is 8-12 weeks. So you should be okay there.
Overall it sounds like you are clear.
Really want to be sure you can do the Hepatitis B again at 23 weeks. But that is just because they give you a range of the 45-160 days. If you didn't have the liver enzyme test done it is up to you if you want to add that you can. If your other tests were negative you are good.
