Is no news good news

Got some urine/swab down below test done for a basically sti and she told me 3-5 business days I'll hear something back. Well today marks day 5 and I'm a little concerned now. Last month a friend of mine gave me oral and he told me without any hesitation that he got tested in January. Plus he hasn't had done anything with anyone since almost a year. He's the type of person to get tested once a year which with me I get it done twice a year (every 6 months). The clinic dr didn't say she saw anything unusual just clear discharge. I'm freaking out a little because this is a new clinic I got it done at and not my normal one since they're closed still do to Covid-19. He assured me everything is fine and told me I'm overthinking and overreacting. He reassures me almost every day because I keep talking about

Update: After pretty much harassing the clinic office by calling multiple times and them catching attitude with me, they gave me my results and everything is Negative
