This really resonates with me because I went through almost the same routine when my partner’s coworker exposed her, and by default me too. The urge to test immediately is strong because nobody wants to sit around with uncertainty. But I learned from experience that early negatives don’t mean much. I tested day two and it was negative, but by day six my body ached all over and that second PCR caught it right away. Now I stick to a kind of personal rule: if I have symptoms, I test immediately, but if not, I wait at least five days after exposure. It seems to match what doctors recommend too, since the virus needs time to multiply before showing up reliably in lab results. Reading a bit about how viruses replicate actually helped me accept the waiting. When I looked into the
definition of retrovirus, it gave me a clearer picture of why testing too early is almost pointless—it’s not that the test is broken, it’s that the virus hasn’t built up enough material yet. Another tip from my side: don’t put all your trust in antigen kits if you’re early on, because they missed my infection twice even when I was already contagious. I’d say treat PCR testing as part of a timeline rather than a one-time guarantee. Plan for two tests if you’ve been exposed, listen closely to your body, and avoid the trap of thinking one negative automatically means you’re safe.
