I got unprotected oral sex from a sex worker at the beginning of January. I had a PCR DNA test at 19 days and it was negative. I also just went and had the hom acces at 6 weeks and it was negative. Is that enough for me to move on? How should I judge weeks? If this happened on January 4th, meaning that last week was my 6th week after potential exposure and I have started 7th week, can I rest easy.
