I hope this make sense

apparently I’ve been tested for bv and chlamydia but there was no , I mean no symptoms at all!!!, usually those things show, at least that what I thought. How tf does that work how am I suppose to know I have something if it doesn’t show. ( I also used boric acid because when I was having sex the condom threw me off and gave me a weird smell after a couple days ) could that be why the symptoms didn’t show?? It was literally a one time use if it’s an infection shouldn’t it cancel the boric acid out and show I have something wrong ???
