Get tested

Should I tell my boyfriend I’m getting tested for HIV? I didn’t cheat on him or anything I work in a healthcare setting. So,I’m getting tested just to be on the safe side.. I just got tested a couple of days ago and I have to come back in 6 months. I feel like I should tell him but I’m super scared! Also idk if I should keep it to myself until I get the test results or tell him now...
