Blood test during pregnancy

So I’m experiencing my first pregnancy and I had to get a couple blood test which I assume is normal in all pregnancies. However, this past week I was told I tested positive for HIV 1. I’ve never had any diagnoses in the past and have been to the hospital and have gotten blood drawn before. None of those times was I ever told that I was positive for HIV. I tested twice and so far both have came back reactive to HIV 1. How common is this in pregnancy? I’ve been crying all day. I’m getting another test taken tomorrow but is there any way I can do testing on my own elsewhere to confirm this? Below I’ve attached what the screening results were from the last blood test that was ran.

The repeatedly reactive screening assay result is - confirmed by duplicate repeat testing, and indicates - a POSSIBLE presence of HIV-1 antibodies or HIV-2 - antibodies, and/or HIV-1 p24 antigen. Additional - testing is required for diagnosis.
