what are my chances of hiv? Scared as fuck.

Ok so I don't know what's going on.My boyfriend got tested and the the lab had to re-do the test because it resulted positive, so they redid it to be sure.The first time we had sex was 2 months ago, and we've used condoms every single time. The only thing that was kind of unprotected was oral and rimming, he rimmed me and he swallowed my cum (lmao a little graphic maybe?), but as of penetration it's always been with a condom.I only had unprotected sex with a guy 1 year ago but he told me he wasn't infected, although now I'm doubting this. He swore he wasn't infected but I don't know anything anymore. The guy didn't even finish, if it helps my chances at all.My boyfriend had sex with another person 5 months ago (before we met) and only had unprotected sex with somebody who had been tested (or he said so) and was negative. I'm scared because I don't know if I may have it or what, are there cases where somebody re does the test and gets negative? We decided to not have sex until the results come back but other than that I don't know what to do.ANYTHING helps, thanks for reading.
